Daco Harkes 77dc74bcd5 [vm/ffi] Support packed Structs

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.
