Daco Harkes 663357209c [vm/ffi] Introduce Abi
This introduces the application binary interface (ABI) concept to
`dart:ffi` as a class with opaque instances.

We will use this for providing mappings for ABI-specific types.
Bug: https://github.com/dart-lang/sdk/issues/42563
Bug: https://github.com/dart-lang/sdk/issues/42816
Closes: https://github.com/dart-lang/sdk/issues/45254

Later, we might open up the contents of `Abi` if need be.

Some API design discussion notes:
