fix(esp_hw_support): Fix incorrect PMA configuration for ESP32-P4

Browse Source 
- As the PMA entry that made some memory regions cacheable was
assigned the highest priority, some intermediate inaccessible
memory regions bypassed protection.

- Added tests for the same

- Verified that even after changing the priority of the PMA entry,
a write operation at SOC_IRAM_LOW + 0x40 (a random RAM cached address)
still needs the same number (29) of CPU cycles.
