fix(mmap): fixed mmap read data wrong when flash being erased/written and cache not disabled
Closes IDFGH-14084
See merge request espressif/esp-idf!29804
Add async color convert coverage for direct RGB24/BGR24 byte-order swaps
and
thread both TX and RX CSC state through DMA2D transactions for future
extensibility.
Add KASAN support for detecting heap memory safety bugs (buffer
overflows, underflows, use-after-free) at runtime using compiler
instrumentation and shadow memory. Gated behind
CONFIG_IDF_EXPERIMENTAL_FEATURES, with touch points kept to esp_system
and heap so other components stay untouched.
- Core runtime (esp_system/kasan.c, esp_kasan.h): nibble-based shadow
memory in DRAM, poison/unpoison, per-access validation, and __asan_*
stubs; hot-path stubs in IRAM so they stay valid with the flash cache
off. Shadow init runs before heap bring-up.
- Heap integration (heap/heap_kasan*.c): alloc/free hooks add redzones,
a quarantine FIFO, and shadow updates.
- Panic handling: disable checks once at the panic handler entry so
backtrace and stack dumps can read redzones without nested reports.
- Build system: -fsanitize=kernel-address for app code, with HAL, SoC,
esp_rom, SPI flash, esp_hw_support, bootloader_support, FreeRTOS, and
heap internals excluded from instrumentation.
- Test app (tools/test_apps/system/kasan_test): Unity tests for
overflow, underflow, use-after-free, and all sized __asan_* stubs,
with halt and no-halt configurations.
- Docs: document KASAN in the heap memory debugging guide (EN and CN).
Define per-target SDIO slave descriptor buffer limits in the LL layer and validate queued send buffers against the 4-byte aligned effective maximum. Update the public docs to describe the chip-dependent limit instead of hardcoding 4092 bytes.

Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.

Embed a 720p BGR raw asset and stream the encoded JPEG over UART so
this example no longer depends on SD card setup.
Add pytest coverage that reconstructs the JPEG from base64 output and
compares it against a checked-in golden image.
