refactor(build): remove enabling feat

All mandatory FEAT_* enabling is done from arch_features.mk.
Remove some old code which would enable some mandatory options based
on arch-features option passed to march appending.

This is now not needed anymore since if we are using correct
ARCH_MAJOR/MINOR the mandatory options will taken care from
arch_features.mk

fix(build): march handling with arch-features

Currently all march compiler option handling is moved to build
utility in march.mk.

We pass arch-features to build which appends to march options,
so this should be done once we decide march options and moving
it to march.mk file.

feat(cpufeat): add feature detection for FEAT_CSV2_3

This feature provides support to context save the
SCXTNUM_ELx register. FEAT_CSV2_3 implies the implementation
of FEAT_CSV2_2. FEAT_CSV2_3 is supported in AArch64 state only
and is an optional feature in Arm v8.0 implementations.

This patch adds feature detection for v8.9 feature FEAT_CSV2_3,
adds macros for ID_AA64PFR0_EL1.CSV2 bits [59:56] for detecting
FEAT_CSV2_3 and macro for ENABLE_FEAT_CSV2_3.

refactor(mte): deprecate CTX_INCLUDE_MTE_REGS

Currently CTX_INCLUDE_MTE_REGS is used for dual purpose,
to enable allocation tags register and to context save and restore
them and also to check if mte feature is available.

To make it more meaningful, remove CTX_INCLUDE_MTE_REGS
and introduce FEAT_MTE. This would enable allocation tags register
when FEAT_MTE is enabled and also supported from platform.

Also arch features can be conditionally enabled disabled based on
arch version from `make_helpers/arch_features.mk`

build: prefer `gcc-ar` over `ar`

The `gcc-ar` wrapper exists to make it easier to support LTO on some
versions of GCC. The two commands are compatible, accepting exactly the
same arguments, so this change moves us to `gcc-ar` to ensure that we
are configuring LTO correctly.

build: always use the C compiler to preprocess

We're a bit inconsistent about which tool we use to preprocess source
files; in some places we use `$(CC) -E` whilst in others we use `cpp`.

This change forces all invocations of the C preprocessor to use the
first scheme, which ensures that the preprocessor behaves the same way
as the C compiler used when compiling C source files.
