refactor(rmmd): plat token requests in pieces

Until now, the attestation token size was limited by the size of the
shared buffer between RMM and TF-A. With this change, RMM can now
request the token in pieces, so they fit in the shared buffer. A new
output parameter was added to the SMC call, which will return (along
with the size of bytes copied into the buffer) the number of bytes
of the token that remain to be retrieved.

TF-A will keep an offset variable that will indicate the position in
the token where the next call will retrieve bytes from. This offset
will be increased on every call by adding the number number of bytes
copied. If the received hash size is not 0, TF-A will reset the
offset to 0 and copy from that position on.

The SMC call will now return at most the size of the shared buffer
in bytes on every call. Therefore, from now on, multiple SMC calls
may be needed to be issued if the token size exceeds the shared
buffer size.

feat(rme): change the default max GPT block size to 512MB

Previously the max GPT block size was set to 2MB as a conservative
default. For workloads making use of SMMU in Normal world, and has
a Stage 2 block mapping of large sizes like 512MB or 1GB, then a
max GPT block size of 2MB may result in performance regression.
Hence this patch changes the default max GPT block size from 2MB to 512MB.

feat(cpufeat): add new feature state for asymmetric features

Introduce a new feature state CHECK_ASYMMETRIC to cater for the features
which are asymmetric across cores. This state is useful for platforms
which has architectural asymmetric cores (A feature is only present in
one type of core e.g. big).
This state is similar to FEAT_STATE_CHECK (dynamic detection) except
that feature state is also checked on each core during warmboot path and
override the context (just for asymmetric features) which was setup by
core executing CPU_ON call.

Only Non-secure context will be re-checked as secure and realm context
is created on same core.

fix(romlib): wrap indirectly included functions

The problem that this resolves is a bit involved; the following
must be met at the same time for some function <to_be_wrapped>:

* to_be_wrapped must be specified as part of the romlib
* to_be_wrapped must _not_ be referenced by any translation unit
in TF-A
* to_be_wrapped must be referenced by a translation unit in a
dependent library, mbedtls for example.

Under these circumstances, to_be_wrapped will not be wrapped, and
will instead reference its original definition while simultaneously
residing in romlib.

This is a side effect of two issues with romlib prior to this patch:

1 to_be_wrapped is expected to wrap by duplicating its definition.
This causes any condition that links against both the base and
wrapper functions to be a link error (duplicate symbol definition).
2 to_be_wrapped is in its own translation unit
This causes the wrappers to be used by TF-A in an as needed.

The duplicate function definitions can be worked around using the
linker's `--wrap` flag, which redirects all references to a symbol
to resolve to `__wrap_<symbol>` and the original symbol to be
available as `__real_<symbol>`. Most of the changes handle creating
this arguments and passing them to the linker.

Further, once you use the linker's wrap, you will encounter another
issue: if TF-A does not use a function, its wrapper is not present.
This causes link issues when a library and not TF-A uses the wrapper.
Note that this issue would have been resolved previously by ignoring
the wrapper and using the base definition.

This further issue is worked around by concatenating the assembly for
all of the wrappers into a single translation unit. It's possible to
work around this issue in a few other ways, including reordering the
libraries passed to the linker to place libwrapper.a last or grouping
the libraries so that symbols from later libraries may be resolved
with prior libraries.

I chose the translation unit concatenation approach as it revealed
that a jumptable has duplicate symbols within it.
