Richard Smith 31919afa24 Allow conversion between T* and Cpp.void*. (#6575) ...

Support an implicit conversion from `T*` to `Cpp.void*` and to `const
Cpp.void*`, and an `unsafe as` conversion in the opposite direction.

In order to support C++ calls taking and returning `void*` (which get
mapped to Carbon `Optional(Cpp.void*)`, also support conversions from
`Optional(T)` to `Optional(U)` if there's a conversion from `T` to `U`.

Fix a bug in `OptionalStorage` for `T*` where its `HasValue` was exactly
backwards.
