df4195062d change(system): heap_caps_alloc returns aligned memory if caps indicate a need for it 
The implicit promise of heap_alloc_caps() and friends is that the memory it
returns is fit for the purpose as requested in the caps field. Before
this commit, that did not happen; e.g. DMA-capable memory wass returned
from a correct region, but not aligned/sized to something the DMA subsystem
can handle.

This commit adds an API to the esp_mm component that is then used by the
heap component to adjust allocation alignment, caps and size dependent on
the hardware requirement of the requested allocation caps.

5dc0481d21 heap: add documentation about the function placement in IRAM and its usage in ISR 
This commits adds a internal.md file in the heap directory to clarify the idea behind
which functions is placed in IRAM or in flash.

A section in mem_alloc.rst documentation is added to specify which functions from the
heap component API can be used in interrupt handlers.

e1f27cf31b heap: remove misleading info about malloc being equivalent to heap_caps_malloc(p, MALLOC_CAP_8BIT)
