Armando 29ae238845 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.

esp_hw_support

This component contains hardware-related operations for supporting the system. These operations are one level above that of hal in that these(1) use system services such as memory allocation, logging, scheduling or (2) may be multi-step operations involving/affecting multiple parts of the SoC.

Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
