Alyssa Rosenzweig 04805f351b JIT: rewrite pdep implementation 
- use better algorithm that is O(# set bits) instead of O(# total bits)
- eliminate spilling by careful management of our temporaries
- fix nzcv clobber bug (whoops)

Ryan Houdek c5ffc0664d Linux: Implements a fault safe memcpy routine 
We are required in our syscall emulation to handle cases where pointers
are invalid. This means we need to pessimistically assume a memcpy will
fault when reading application memory.

This implements a signal handler based approach to catching the SIGSEGV
on memcpy and returning an EFAULT if it faults.

RCL/RCR.

Billy Laws 407e26bfee FEXCore: Use TMP1-4 for values that need preserving across spills 
The ARM64EC SRA layout will use x0-3 for x86_64 registers, as such any
arguments passed to C ABI functions need to proxy their arguments
through the temporaries and move as appropriate.

Tony Wasserka b08d372c78 Thunks: Fix definition of GUEST_THUNK_LIBRARY 
The -deps target is the wrong target to add this to, since its compile flags
are propagated to both Guest.cpp and Host.cpp. Instead, define the flag only
when processing files within a guest context.

Gustavo Muniz f6ff6c8b44 Improvements to the Dockerfile 
I added the `pkg-config` that is missing in the Dockerfile, and make the git clone the repository direct from the image, so the user don't need to clone it manually and after that pulls inside the Dockerfile!

Ryan Houdek a6c57f71e9 SpinWaitLock: Fixes potential extra wait that would occur on contended lock 
We had a chance of doing an additional bogus wfe if the expected value
was hit in one iteration of a loop. Not the biggest problem on current
hardware where WFE only ever sleeps for 1-4 system cycles, but on future
hardware where WFE might actually sleep for longer then this could have
been an issue.

Tony Wasserka 6eaeb48fac Thunks/gen: Implement assisted struct repacking 
This can be used to allow automatically handling structures that require
special behavior for one member but are automatically repackable otherwise.
The feature is enabled using the new custom_repack annotation and requires
additional repacking functions to be defined in the host file for each
customized member.
