Explicitly describe the statistics PTA ABI using dedicated inline
comments and moving struct pta_stats_ta and struct pta_stats_alloc
from respectively tee_ta_manager.c and malloc.h to pta_stats.h

For that purpose, define ALLOC_ID_* macros to identify each allocator
one can query information from through the statistics PTA API.

In case of TA_RAM defined at the end of address range,

The size must be used rather than the high address to
avoid this overflow issue. Update the corresponding files due
to API modification.

mobj_reg_shm represents registered shared memory. This is basically
a list of pages provided by normal world. It can be used to pass
memory parameters to TAs.

mobj_mapped_shm is built on top of mobj_reg_shm. It is almost
the same thing, but it is mapped to OP-TEE virtual address space,
so OP-TEE kernel can access such buffers.

Adds the following statistics to the heap allocator and export then via
the static TA `core/arch/arm/sta/stats.c` (all of them can be reset):

- num_alloc_fail: number of calls to malloc()/calloc()/realloc() that
returned NULL
- biggest_alloc_fail: the size in bytes of the largest allocation
request that resulted in a failure
- biggest_alloc_fail_used: the number of bytes that were allocated at
that time

Depends on CFG_WITH_STATS=y.
