Replaced per-target bootloader.ld.in with bootloader.memory.ld.in and
bootloader.sections.ld.in.
Common code moved to file bootloader.sections.common.ld
Unify ESP32-P4 ECO4- and ECO4+ linker scripts into one shared script
Revision-specific code is selected with CONFIG_ESP32P4_SELECTS_REV_LESS_V3
For the bootloader build, the `priv_include_dirs` variable is
uninitialized, but it is used in the common call to
`idf_component_register`.
Using uninitialized variables is not allowed in cmakev2 because a
component may be evaluated in the context of another component’s
variable scope.

When CONFIG_APP_BUILD_TYPE_RAM is set (loadable ELF app build),
bootloader_support was adding micro-ecc to priv_requires. The micro-ecc
component lives in the bootloader subproject and is not available in
normal app builds with cmakev2, causing component resolution to fail
when built for a build system v2 project.
micro-ecc is only needed for secure boot sources built under
BOOTLOADER_BUILD (secure_boot_signatures_bootloader.c). For app builds
with CONFIG_APP_BUILD_TYPE_RAM we do not build those sources, so
only add micro-ecc to priv_requires when BOOTLOADER_BUILD is set.
This commit reorganizes SPI flash header files to better reflect their
visibility and intended usage:
1. Rename `esp_flash_port/` to `esp_flash_chips/`:
- Better reflects that these headers are for chip driver implementations
- All chip driver headers moved to `esp_flash_chips/` directory
- Added README.md explaining semi-public nature of these headers
2. Move internal headers to `esp_private/`:
- `esp_flash_internal.h` -> `esp_private/esp_flash_internal.h`
- `memspi_host_driver.h` -> `esp_private/memspi_host_driver.h`
3. Move chip driver related headers to `esp_flash_chips/`:
- `esp_private/esp_flash_types.h` -> `esp_flash_chips/esp_flash_types.h`
- `spi_flash/spi_flash_defs.h` -> `esp_flash_chips/spi_flash_defs.h`
- `spi_flash_override.h` -> `esp_flash_chips/spi_flash_override.h`
- All `spi_flash_chip_*.h` headers moved to `esp_flash_chips/`
4. Code improvements:
- Remove unused includes (e.g., `spi_flash_override.h` from `cache_utils.c`)
- Use public API `esp_flash_get_size()` instead of direct member access
- Add `esp_flash_is_quad_mode` to linker.lf for IRAM placement
5. Documentation updates:
- Add README.md in `esp_flash_chips/` explaining semi-public headers
- Update programming guide with warnings about internal headers
- Update both English and Chinese documentation
6. Update all references across the codebase:
- Update includes in `spi_flash` component
- Update `bootloader_support`, `app_update`, `esp_tee`, `espcoredump`
- Update example projects
Breaking changes:
- Headers moved to new locations require include path updates
- `custom_flash_driver` example temporarily disabled until external
components are updated
