Closes: https://github.com/dart-lang/sdk/issues/38158
This CL implements unaligned access for float/double on arm32, but does
not expose it in an API. Rather it only uses these loads/stores inside
the getters and setters of packed structs.
Bug: https://github.com/dart-lang/sdk/issues/45009
Besides unaligned access for float/double, this CL is mostly a CFE
change. The only VM change is reading the packing in the
`_FfiStructLayout` annotation.
The implementation of using the packing in the VM, and analyzer changes
have landed separately in earlier CLs.

This CL is a code cleanup landed separately from https://dart-review.googlesource.com/c/sdk/+/129081 to make the CL size smaller.
Refactorings:
* Split up runtime/vm/compiler/ffi.{cc,h} in multiple files.
* Move FrameRebase to compiler/ffi and prevent it from modifying Locations.
* Remove use of <algorithm>.
