Three gaps kept `mod.f[T](x)` from compiling:
- get_func_name now unwraps a Subscript callee to its base name, so an
expression statement like `f[int](x)` / `mod.f[int](x)` reaches the
normal call path instead of failing name resolution. Generic class
constructors and type subscripts still return None, keeping their
dedicated paths.
- the generic-call dispatcher resolves `Attribute` bases inside the
subscript (`temp.array2list[int]`) to the defining module's SHA1, and
treats it as a module-qualified template lookup.
- inference understands pointer/array annotations around the type
parameter: `_annotation_refers_type_param` walks PtrT/ArrayT wrappers
and tuple slices, and inference peels as many pointer/array layers off
the argument as the parameter annotation wraps around T, so
`array2list(l, ...)` with `array: T*` and `l: []int` infers int.
Self-host: 110/110 with the new compiler building itself; GenericTest,
GenericTest3, GenericTest4, VectorGenericTest and ListTest pass.
