Subject: [PATCH] feat(heap): move TLSF ROM patches and related files from
 esp_rom to heap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TLSF ROM patch code (rom_patch_tlsf.c, rom_patch_multi_heap.c),
their headers, and the per-target *.rom.heap.ld linker scripts are
semantically owned by the heap component, not esp_rom. Move them
accordingly:

- components/esp_rom/patches/esp_rom_tlsf.c
  → components/heap/rom_patches/rom_patch_tlsf.c
- components/esp_rom/patches/esp_rom_multi_heap.c
  → components/heap/rom_patches/rom_patch_multi_heap.c
- components/esp_rom/include/esp_rom_tlsf.h
  → components/heap/rom_patches/include/rom_patch_tlsf.h
- components/esp_rom/include/esp_rom_multi_heap.h
  → components/heap/rom_patches/include/rom_patch_multi_heap.h
- components/esp_rom/<target>/ld/<target>.rom.heap.ld (×8)
  → components/heap/port/<target>/ld/<target>.rom.heap.ld

Update heap/CMakeLists.txt to:
- use target_linker_script() directly for *.rom.heap.ld
- guard post-registration ROM patch setup with NOT BOOTLOADER_BUILD
- drop stale CONFIG_HEAP_TLSF_CHECK_PATCH symbol reference
- drop esp_rom_include_multi_heap_patch from TLSF_CHECK_PATCH guard

Remove the corresponding entries from esp_rom/CMakeLists.txt.
