732a657694 Change Config to make fastmem_pointer of zero valid. 
This changes Dynarmic::A32/A64::Config to store fastmem_pointer in
a std::optional<uintptr_t>, allowing the user to pass a zero base
address for the guest memory, which can be used to effectively
implement a shared address space between the host and the guest.

043f21df7d tests/A64: Update {S,U}SHL tests 
Converted tests to use oaknut, and added some extra test cases. SSHL's
additional tests are targetd to make sure that the sign of the lowest
byte is used to determine shift direction, not the entire element. USHL
targets this as well as just having more negative (right shift) cases in
general.

4ae4750b5a emit_arm64_a64: Take into account currently loaded FPSR 
Previously we just retrieved the last stored FPSR and used that when the guest asks for the current FPSR.
This is incorrect behaviour. We failed to take into account the current state of the host FPSR.

Here we take this into account. This bug was discovered via #795.

ee84ec0bb9 backend/x64: Reduce races on invalidation requests in interface 
This situation occurs when RequestCacheInvalidation is called from
multiple threads. This results in unusual issues around memory
allocation which arise from concurrent access to invalid_cache_ranges.

There are several reasons for this:
1. No locking around the invalidation queue.
2. is_executing is not multithread safe.

So here we reduce any cache clear or any invalidation to raise a
CacheInvalidation halt, which we execute immediately before or
immediately after Run() instead.
