core: add thread_count to thread_init_threads()

Add a thread_count parameter to thread_init_threads(). This must currently
always be equal to CFG_NUM_THREADS, but may become a dynamic configuration
parameter with CFG_DYN_CONFIG=y in later patches.

The array threads[] is changed into a pointer to allow dynamic
allocation in later patches. The assembly code is updated accordingly to
handle a pointer instead of an array.

core: add core_count to thread_init_thread_core_local()

Add a core_count parameter to thread_init_thread_core_local() to enable
dynamic configuration of the number of supported cores when configured
with CFG_DYN_STACK_CONFIG=y, or it must be equal to
CFG_TEE_CORE_NB_CORE. This is needed in later patches where the number
of cores is configured dynamically.

The array thread_core_local[] is changed into a pointer to allow dynamic
allocation in later patches. The assembly code is updated accordingly to
handle a pointer instead of an array.

Previously pointer authentication was only supported for TAs. With this
patch add a configuration option CFG_CORE_PAUTH to enable support for
core. Each privileged thread has its own APIA key. There are also a
separate APIA key for each physical core used when handling an abort or
when using the tmp stack.

core: suppress text relocation on stack_tmp_export

stack_tmp_export is a pointer so it is associated with a dynamic
relocation when position-independent code is generated (ASLR). Moreover,
this symbol is in the .identity_map section, which is part of .text after
the final link. To get rid of this TEXTREL, remove stack_tmp_export and
compute the corresponding value in assembly instead from stack_tmp and
constants defined in core/arch/arm/kernel/asm-defines.c.
