Ryan Houdek 44e06185b7 FEXCore: Stop leaking AVX configuration state
The dispatcher was saving AVX state even though FEX doesn't support it
currently. This is due to it checking for the config option rather than
the HostFeatures option.

The `EnableAVX` config option is supposed to be used to inform FEXCore
if we want AVX disabled or not when the host supports the feature. In
this case it is universally enabled because we haven't encountered any
games that have issues with AVX state being saved with signals. (We know
they exist, we just don't have configurations for them).

The HostFeatures option `SupportsAVX` is the option that is supposed to
be getting used for determining if the runtime AVX feature is enabled.
This also had an issue though that this was **also** always enabled if
running on an x86 host with AVX, or an ARM host with SVE2-256bit.
It was then disabled if the config option was disabled; But, since
FEX-Emu doesn't support AVX fully yet, we need to ensure this isn't yet
enabled.

But this only solves half the problem. In order for our CI to test AVX
features before fully supporting AVX, it needs to be able to enable AVX
so that the CPU state is correctly saved.

So we need to change the default configuration option to be false, and
have CI enable it for the tests that matter before AVX is fully
implemented.
