  [lldb][AArch64][Linux] Show MTE store only setting in mte_ctrl (#145033)

This controls whether tag checking is performed for loads and 
stores, or stores only.

It requires a specific architecture feature which we detect
with a HWCAP3 and cpuinfo feature.

Live process tests look for this and adjust expectations
accordingly, core file tests are using an updated file with
this feature enabled.

The size of the core file has increased and there's nothing
I can do about that. Could be the presence of new architecure
features or kernel changes since I last generated them.

I can generate a smaller file that has the tag segment,
but that segment does not actually contain tag data. So
that's no use.
