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.

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.
Default timeout for interrupt WDT was increased by default
on ESP32, due to some heap integrity check APIs taking a long
time on large PSRAMs and causing timeouts.
But this adjustment was only done for ESP32, not later chips,
even though they may experience the same issue.
Adjusted to have the same behavior on all chips with PSRAM
enabled, making it consistant with the docs.

Add a blocking wrapper for async memcpy so simple users can wait for one DMA copy without writing their own ISR callback and semaphore plumbing. Update functional tests and documentation to use the simpler API where async completion handling is not needed.

The Linux LWIP port was using --wrap linker flags to intercept read,
write, close, fcntl and select, routing socket FDs (>= LWIP_SOCKET_OFFSET)
to lwip_*() functions. This conflicted with the dlsym(RTLD_NEXT)
cooperative syscall interposition used by the new FreeRTOS Linux
simulator.
Replace the --wrap approach with esp_vfs_register_fd_range(), matching
how LWIP already integrates with VFS on bare-metal ESP32 targets.
The cooperative read()/write() wrappers in vfs_coop_syscalls.c check
VFS first, so LWIP FDs are dispatched to lwip_read() etc. before the
cooperative fallback path is reached.
After startup is done and app_main is reached, all calls to
heap_caps_add_region_with_caps (adding a new heap to the list of registered
heaps) will not affect the minimum free heap size value.
For heaps created before startup, this won't apply and their size will
end up being taken into account in the calculation of the minimum.
Refactor the esp_err_to_name() system to decouple esp_common from
higher-level components. Instead of a monolithic generated table,
each component registers its error codes into a dedicated linker
section (.esp_err_msg_table) via idf_define_esp_err_codes() in its
CMakeLists.txt.
New files:
- tools/err_codes_extract.py: extract ESP_ERR_* defines from headers to CSV
- tools/err_codes_to_c.py: generate C source placing entries into linker section
- tools/err_codes_to_rst.py: generate RST documentation from error codes
- tools/cmake/err_codes.cmake: CMake module providing idf_define_esp_err_codes()
- components/esp_common/include/esp_err_codes.h: esp_err_msg_t typedef
- components/esp_common/src/esp_err_to_name_new.c: new lookup using link-time array
- tools/test_apps/build_system/err_codes_check/: CI test app
Changes:
- Remove all optional component dependencies from esp_common/CMakeLists.txt
- Add .esp_err_msg_table section to all 5 linker scripts
- Register error codes in 18 components via idf_define_esp_err_codes()
- Add new scripts to .gitlab/ci/rules.yml build_check patterns
- use new scripts to generate doc and add CI validation
- Update esp_err.rst to add description of composable code registration
