OpcodeDispatcher: Minor optimization to small pushf
...
The push operation already truncates the result, there's no need to bfe
it. Noticed this while cleaning up in #4134 . Removes one instruction for
16-bit and 32-bit pushf instructions.

According to
https://github.com/rust-lang/rust/commit/c064b6560b7ce0adeb9bbf5d7dcf12b1acb0c807
turns out that the arm yield instruction is effectively a nop on all
reasonably new CPUs.
Instead switch over to wfe because it matches x86 `PAUSE` semantics more
closely.

Linux: Optimize CreateNewThread stack usage
...
We were creating a copy of the FEXCore::Core::CPUState object when we
didn't need to. We can pass the host thread's CPUState frame through to
the creation handlers since it's read-only (so modify it to be const).
We then just move the RAX and RSP setting to /after/ the CreateThread
handling instead of before.
This reduces stack usage from ~1392 bytes to ~80 bytes.
