This CL changes the semantics of
`Pointer<T extends NativeType>.elementAt` and
`sizeOf<T extends NativeType>` to use the compile-time `T` rather than
the runtime `T`.

The analyzer and CFE now report a warning on calls to
`Pointer<T extends NativeType>.elementAt()` and
`sizeOf<T extends NativeType>()` where `T` is a generic.
Adapted from https://dart-review.googlesource.com/c/sdk/+/178200 to
only deprecate but not error out on generic calls.
Does not roll forward `package:ffi` to a version with the `Allocator`
but keeps the generic `sizeOf` invocation. This causes extra warnings
in the pkg/front_end testcases.

Introduces the Allocator API in `dart:ffi`.
This CL does not yet roll `package:ffi` to use `Allocator`, because that
breaks the checked in Dart in Fluter in g3. Instead, this coppies
`_MallocAllocator` from `package:ffi` into the ffi tests for testing.
This CL does not yet migrate off `allocate` and `free` in the SDK. That
is done in a dependent CL.

This CL creates nnbd versions of the tests and runs them on the nnbd sdk.
This CL does not (1) migrate sdk_nnbd/lib/ffi fully yet, and does not (2) fix all the tests/ffi (which is NNBD tests) yet.
