LogWindow: Fix the timer event bindings
Disables NEON optimized instructions.
These are causing issues in games. In particular you get pink on the screen in Animal Crossing.
Disable until fully investigated.

This also disables fastmem on floating point loadstore instructions which are horribly broken and won't actually backpatch when an invalid read/write
is encountered.
Enables the ARMv7 FPR cache.

The problem instructions with the FPR are disabled in the previous commit. This can now be reenabled for fairly large performance gains.
Enables ARMv7 build options entirely on ARM.

We only support ARMv7 with Dolphin, so if we are building on ARM have our target be for armv7-a.

Reenables the ARMv7 FPR cache + minor ARMv7 things.
