3118120659 esp_hw_support: Update memory ptr location/property checks
- to acknowledge the unused DCACHE added to DRAM for ESP32-S3

- For ESP32-S3, when the DCACHE size is set to 16 kB, the unused 48 kB is added to
  the heap in 2 blocks of 32 kB (from 0x3FCF0000) and 16 kB (from 0x3C000000).
- But, if we try allocating memory from the 16 kB block and run an `esp_ptr_internal`
  check on that memory pointer, it fails as the address block from 0x3C000000
  corresponds to the external memory symbols SOC_DROM_LOW and SOC_EXTRAM_DATA_LOW.
  (E.g. freertos - If the IDLE task stack buffer gets allocated from this region,
  the firmware will abort due to this failure).
- Thus, the checks `esp_ptr_internal`, `esp_ptr_in_drom` and `esp_ptr_byte_accessible`
  have been updated to acknowledge this memory as a part of the DRAM.

2d44dc1eed mmu: driver framework, for vaddr maintenance
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.

This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.
