Add a static key to exapnd the logic of system_supports_mte().
This function controls mte enablement in both EL1 and EL0.
The static key, "arm64_mte_support" is default true and can
be disabled via the early_param.

Please could we use the id-reg override mechanism and give it
an alias ?
See :
arch/arm64/kernel/idreg-override.c
And could add something along the lines of :
arm64.nomte
Cheers
