core: pta: stats: get RPMB secure storage allocation stats

Retrieve RPMB secure storage space allocation statistics from
PTA stats STATS_CMD_ALLOC_STATS command.

STATS_NB_POOLS is intentionally not incremented since it is
expected to give the number of pools which IDs start from 1
(ALLOC_ID_HEAP), not from 0 (ALLOC_ID_ALL) that is a magic
ID.

Ensure the stats are all 0 for when RPMB_FS is not supported or we
failed to get the stats info. For this, let's zero initialize the
shared buffer so that these default stats also apply on other stats
that may not be reachable (deprecate public DDR pool, Nexus heap).

tree wide: clarify PTA ABI

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
header file.

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