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.
