docs(simd): introduce CTX_INCLUDE_SVE_REGS build flag

This patch documents the support for the newly introduced
CTX_INCLUDE_SVE_REGS build flag. Since this build flag is influenced
by other build flags, the relevant sections have been updated with
proper guidance.

This patch also documents the SEPARATE_SIMD_SECTION build flag.

that disable TRBE but only implemented helper functions that are
used to detect cores affected by Errata 2938996(Cortex-A520) & 2726228(Cortex-X4)

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.

Various SPMC projects within trustefirmware.org have decided to adhere
to a common FF-A manifest binding document. The one hosted in the
readthedocs portal of TF-A project will be considered as the reference.

Hence, this binding document is updated to reflect new additions made
to binding document hosted in Hafnium project. Eventually, all other
binding document are going to be removed.

Also, few fields were incorrectly identified as mandatory. Necessary
corrections are made in this patch.

feat: add creating transfer lists from yaml files

This commit adds a command create-from-yaml to tlc, which
creates a transfer list from a yaml file. It also changes
the files structure of the fixtures in the unit tests so
they are in a directory called trusted-firmware-a. This
is necessary because blob file paths in the yaml file are
relative to the root of TF-A.

The blob files are not verified by TLC, so it can be used
to load arbitrary binary information into the transfer
list. The authenticity of the transfer list must be
ensured by the loader.
