This change limits ta_private_vmem_end to TA segments defined when
TA is loaded.

Currently 'ta_private_vmem_end' only used to prevent a TA from exposing
its code/data/stack memory to another TA it invokes. A shared memory
buffer passed as TA invocation parameter is obviously not inside the TA
private memory an can be exposed to another TA.

core: add heap allocation failure statistics

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.

Before this patch the checks of the parameters buffers for a TA where
required to be physical pointers. When a static TA is invoked from a
user TA the virtual addresses of the buffers aren't translated to
physical addresses as they will be translated back to the same virtual
address again. With this patch the parameters buffers are tagged as
containing virtual addresses allowing the checks to take that into
account.
