tools/mpremote: Don't apply Espressif DTR/RTS quirk to TinyUSB CDC dev.
The DTR quirk workaround from dea949e86 is needed for the Espressif
Serial/JTAG device, but not for TinyUSB - in fact DTR must be set for
TinyUSB to correctly determine if the serial port is open (and leads to
issues with lost bytes otherwise).

shared/tinyusb/mp_usbd_cdc: Rewrite USB CDC TX loop.
This is related to the previous commit (where due to the new config flag
this loop could end up stuck indefinitely if the USB host was
disconnected). The previous loop could maybe still get stuck if the
low-level USB state and the high-level USB state got out of sync. (Not
clearly possible, but hard to say definitely not possible.)
To be "belts and braces" careful:
- Always run mp_usbd_task() each time around the loop to progress the
state.
- Always evaluate the timeout if we fail to write anything to the FIFO.

shared/tinyusb: Fix hang from new tx_overwritabe_if_not_connected flag.
This flag is in the main branch of TinyUSB, included in Espressif since
their v0.18.0~3 component release (but it's not actually in TinyUSB v0.18.0
release).
Setting the flag is needed for the USB device not to block waiting for
space in the FIFO if the host is disconnected.

esp32: Add IDF Component Lockfiles to git repo.
This is recommended by Espressif, and it's the only way to ensure
everyone builds the same set of component versions.
The awkward part is that updating the ESP-IDF version will churn a line
in each of these files (and possibly other changes).
Adds a build-time check for lock file changes, which is either a warning or
a hard error depending on the value of MICROPY_MAINTAINER_BUILD
flag (introduced in previous commit).

Also future-proofs this code for other chips. Apart form C6 and C2, all

extmod/machine_i2c_target: Add new machine.I2CTarget class.
This commit implements a generic I2C target/peripheral/"slave" device,
called `machine.I2CTarget`. It can work in two separate modes:
- A general device with interrupts/events/callbacks for low-level I2C
operations like address match, read request and stop.
- A memory device that allows reading/writing a specific region of memory
(or "registers") on the target I2C device.
To make a memory device is very simple:
from machine import I2CTarget
mem = bytearray(8)
i2c = I2CTarget(addr=67, mem=mem)
That's all that's needed to start the I2C target. From then on it will
respond to any I2C controller on the bus, allowing reads and writes to the
mem bytearray.
It's also possible to register to receive events. For example to be
notified when the memory is read/written:
from machine import I2CTarget
def irq_handler(i2c_target):
flags = i2c_target.irq().flags()
if flags & I2CTarget.IRQ_END_READ:
print("controller read target at addr", i2c_target.memaddr)
if flags & I2CTarget.IRQ_END_WRITE:
print("controller wrote target at addr", i2c_target.memaddr)
mem = bytearray(8)
i2c = I2CTarget(addr=67, mem=mem)
i2c.irq(irq_handler)
Instead of a memory device, an arbitrary I2C device can be implemented
using all the events (see docs).
This is based on the discussion in #3935.

rp2/rp2_pio: Fix use of PIO2 in prog data structure.
The RP2350 PIO2 State Machines (8, 9, 10, 11) did not work. The data
structure used to pass the PIO arguments was missing an entry for PIO2,
thus causing the PIO2 instances to write wrong data to wrong locations.
Fixes issue #17509.

rp2/CMakeLists.txt: Fix flash size check logic.
Follow up to 6bfb83e30aa28e7bbfb0f77f378da05b32574f3d, if the variable
`PICO_FLASH_SIZE_BYTES` is not a numeric constant, eg "(2 * 1024 * 1024)",
then it won't pass the GREATER check. So change the if logic to just test
if it's defined.

tools/mpremote: Update ESPxxx detection for USB-CDC ports.
Detection of ESP-XX devices was based on just the names of the USB driver
name, and did not account for the switch of the newer ESP-xx devices to
USB-CDC. On Windows this caused unwanted/unneeded resets as the DTR/RTS
signals are also used for automatic device reset over USB-CDC. See
https://github.com/micropython/micropython/issues/9659#issuecomment-3124704572
This commit uses the Espressif registered VID 0x303A to detect USB-CDC
ports, to enable the same DTR/RTS settings as used on the UART-USB
connection.
Also improved the robustness of the code using `getattr()`.

py/asmthumb: Don't corrupt base register in large offset store.
asm_thumb_store_reg_reg_offset() modifies the base register when storing
with a large offset which triggers the generic path. If a variable lives
in that register, this corrupts it. Fix this by saving the base register
on the stack before modifying it.

py/parse: Add support for math module constants and float folding.
Add a new MICROPY_COMP_CONST_FLOAT feature, enabled by in mpy-cross and
when compiling with MICROPY_CONFIG_ROM_LEVEL_CORE_FEATURES. The new
feature leverages the code of MICROPY_COMP_CONST_FOLDING to support folding
of floating point constants.
If MICROPY_COMP_MODULE_CONST is defined as well, math module constants are
made available at compile time. For example:
_DEG_TO_GRADIANT = const(math.pi / 180)
_INVALID_VALUE = const(math.nan)
A few corner cases had to be handled:
- The float const folding code should not fold expressions resulting into
complex results, as the mpy parser for complex immediates has
limitations.
- The constant generation code must distinguish between -0.0 and 0.0, which
are different even if C consider them as ==.
This change removes previous limitations on the use of `const()`
expressions that would result in floating point number, so the test cases
of micropython/const_error have to be updated.
Additional test cases have been added to cover the new repr() code (from a
previous commit). A few other simple test cases have been added to handle
the use of floats in `const()` expressions, but the float folding code
itself is also tested when running general float test cases, as float
expressions often get resolved at compile-time (with this change).

MinGW-w64 (used on MSYS2) doesn't include `alloca.h`, but `alloca()` is
provided via `malloc.h` instead. And this fix is also needed for other
Windows build systems.
