This patch fixes a bug where integer underflow causes the tests
to wrongly fail.

Since event counts are register values, they are unsigned in TFTF.
When the event count is less on the SMC being profiled than the
baseline SMC event count, subtraction causes an underflow which
goes beyond the allowed deviation and makes the test fail.

This patch provides the following feature and makes
modification listed below:
- ARMv8.3-PAuth tests now check for all keys being in use
 (e.g. APIAKey when the test suite is built with
 `ENABLE_PAUTH=1` option) and program new key values otherwise.

TF-A now has support for the new Memory Tagging Extension in ARMv8.5,
see commit 91624b7fed52 ("Merge changes from topic "jc/mte_enable"
into integration").

This patch creates and enables tests to ensure that the extension is
being properly enabled and that no undesired leakages occur.

This patch provides the following features and makes
modifications listed below:
- `plat_init_apiakey()` function is replaced with `init_apkey()`
  which returns 128-bit value and uses Generic timer physical counter
  value to increase the randomness of the generated key.
  The new function can be used for generation of all ARMv8.3-PAuth keys.
- Source file `pauth.c` moved from `plat/common/aarch64`
  to `lib/extensions/pauth/aarch64` folder which contains PAuth specific
  code.
- Individual APIAKey key generation for each CPU on every warm boot.
- Per-CPU storage of APIAKey added in `tftf_suspend_context` structure.
- APIAKey key is saved/restored in arch context on entry/exit from
  suspended state.
- Added `pauth_init_enable()` function which generates, programs
  and enables APIAKey in EL1/EL2.
- Changes in documentation related to ARMv8.3-PAuth support.

This patch introduces a series of tests that try to leak PMU counter values
from EL3 and S_EL1.

PMU events used:
	- CPU cycles via PMU counter PMCCNTR_EL0
	- Retired writes to PC via PMU counter PMEVCNTR0_EL0

This AARCH64-specific patch is for security fix:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1789



The AARCH32 versions of these tests will be in a future patch.

This patch renames folder and source file names according to

- `ptrauth` folder in `tftf\tests\extensions' renamed to `pauth`,
- `test_ptrauth.c` source file to `test_pauth.c`

Trusted OSes should preserve or fill by zeroes the values of x1-x3
registers across an SMC call in order to prevent data leakage. The
behaviour of OP-TEE regarding to this has changed recently from
preserving values to filling them by zeroes. This patch utilitizes the
newly added allow_zeros[] parameter of the smc_check_match function to
make the tests compatible with OP-TEE commit 6e558fa94ab0 or later.

This prevents the execution of the read-only data.

This is done in a similar way in TF-A when the build flag
SEPARATE_CODE_AND_RODATA is enabled.

The build flag is probably not needed in TF-A Tests.

This patch fixes the bug in tftf_get_total_aff_count()
which incorrectly calculates the number of CPUs for
aff_lvl = 0. The function reads tftf_pd_nodes[] array
only based on condition
`tftf_pd_nodes[node_idx].level == aff_lvl` but
doesn't check for `indexes < PLATFORM_NUM_AFFS`.
This causes reads of the array beyond its boundaries
which results in incorrect calculation of number of CPUs,
and some of the tests entering infinite loops.

The previous implementation could behave incorrectly because of the sign
extension of the char when compared to the int.
