feat(system): add OCD stub bin support for more targets

Browse Source 
Add SOC_DEBUG_HAVE_OCD_STUB_BINS for esp32c5, esp32c61, esp32h4,
esp32h21 and esp32p4. Update TEE linker scripts with
correct esp_tee_app_config offsets for the 0x3000 stub reservation

OpenOCD uses stub code to access flash during programming or when inserting and removing
SW flash breakpoints.

By enabling this option, 12K of memory in RAM will be preallocated with the stub code,
eliminating the need to back up and restore the memory region.
The stub binaries are prebuilt and linked to run at the start of IRAM (_iram_start).
On ESP32-P4 rev >= v3, _iram_start is 0x4FF00000 + L2 cache size, so it only matches the
stub's link address (0x4FF80000) when the L2 cache is 512KB. This option is therefore
only available on ESP32-P4 rev >= v3 when CACHE_L2_CACHE_512KB is selected. Earlier P4
revisions and other targets place _iram_start at a fixed address and are not affected.
