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`
