[program-gen] Fix enum resolution from types of the form Union[string, Enum] and emit fully qualified enum cases (#15696)
# Description

This PR improves enum type resolution from strings. When we try to
resolve `Union[string, Enum]` for a string expression, we choose
`string` because it is the more general type since not every string is
assignable to `Enum`. However, here we spacial case strings that are
actually part of that `Enum`.

The result is that `pcl.LowerConversion` will choose `Enum` from
`Union[string, Enum]` when the value of the input string is compatible
with the enum. This greatly improves program-gen for all of typescript,
python, csharp and go which now will emit the fully qualified enum cases
instead of emitting strings.

Closes https://github.com/pulumi/pulumi-dotnet/issues/41 which is
supposed to be a duplicate of
https://github.com/pulumi/pulumi-azure-native/issues/2616 but that is
not the case (the former is about unions of objects, the latter is
unions of enums and strings)
