48b9a8d6f4 mm/shm: Move the vma allocators to separate functions
This will allow changing the underlying backend, i.e. granule allocator,
to something more efficient, if this is needed later.

Also, it gives easier access to the common SHM book keeping.

458ff380e5 mm/gran: Allow run-time execution of gran_reserve
User can ask for specific granules to be allocated.

This is useful for one thing only: when mmap() is called for a specific
vaddr. The parameter itself is non-sensical, this is just to satisfy
the POSIX standard.

c546c0b647 mm: Do not abort on allocation failue with CONFIG_DEBUG_MM
When allocation failed, it isn't too uncommon for the caller
to fall back to other allocation method.
(eg. esp32 textheap code tries iram heap when an allocation from rtc heap
failed.)
DEBUGASSERT(false) is too much in that case.

This commit removes the DEBUGASSERT, and also makes the heap dump
a separate option.

85f0bc591e mm:initialize ensure alignment.
Broken by 635cfa.

   On an stm32 the heap is formed from
   const uintptr_t g_idle_topstack = HEAP_BASE;
   where HEAP_BASE is &_bss + CONFIG_IDLE_STACKSIZE.

   Both these values are not deterministic. One
   comes from the compiler, the other the system
   configurator.

   a 3 byte bss and 250 byte stack would lead to
   and unaligned address used as the heap to be.

   The compiler used clever `strd r1,r3,[r5,#8]` to
   store 2 values in one memory cycle into the
   heap_impl struct. Resulting in a hardfault.

   Change the amount of bss or the CONFIG_IDLE_STACKSIZE
   could lead to a non-functional NuttX system.
