Odd behaviour with async method declaration: wrong types suggestion

[DoctorKrolic]

Probably related to #60339

Version Used:
VS 2022 v.17.2 Preview 2.1

Steps to Reproduce:
Start code:

class Test
{
    public async $$
}

Expected Behavior:
Only Task, Task<>, ValueTask and ValueTask<> are suggested

Actual Behavior:

This would be a reasonable thing to filter down to. Note: we would want any type with [AsyncMethodBuilder] on it.

@CyrusNajmabadi If you put [AsyncMethodBuilder] on the method itself, does it allow any type or only awaitable types?
