Add CFG_PGT_CACHE_ENTRIES to allow platforms to customize the page

support very large TAs of several dozen of Mbytes of private memory
(code/data).

Move PGT_CACHE_SIZE macro definition from pgt_cache.h to pgt_cache.c
since it is used only in that source file.

OP-TEE currently doesn't support using a different hash for MGF1

(e.g. in EncryptionOperationsTest.RsaOaepWithMGFDigestSuccess [1]).

Pass the MGF1 attribute to crypto implementations. Note that
only libtomcrypt supports this feature at the moment, so other
implementations will either fail or fall back to libtomcrypt when
passed a different MGF1 hash.

...and similar ones for fpcr write, as well as fpsr read and write.

Clang 12.0.0 does not have any problem with this code which makes me
think that it's a Clang/LLVM issue.

Work around the problem by using the coded system register identifiers
S3_3_c4_c4_0 and S3_3_c4_c4_1 instead of fpcr and fpsr, respectively.
The values 3-3-4-4-0 and 3-3-4-4-1 are taken from the Arm ARM sections
C.5.2.8 and C.5.2.9.

core: fix race condition on TA/PTA/StMM context loading

Fix race condition on creation of a context for single instance TAs,
PTAs or StMM application. Such race condition could occur and lead to
duplicated contexts if connected close enough that they are created
after tee_ta_init_session() calls tee_ta_init_session_with_context()
and before the context are added in the centralized context list.

This is realized by keeping tee_ta_mutex held while tee_ctxes list is
looked up for matching a context or a new context is added into that
list with its .is_initializing field activated. For that purpose
user TA and StMM application initialization function are split in
2 functions, the 2nd one used to finalizes the context creation
started in the 1st function.

By the way, add inline description comments and fix indentation issues
in uaer_ta.h and remove the inline comment in pseudo_ta.c that refers
to TA loading whereas the function relates to PTA contexts creation.
