gccrs: improve handling of Self Type paths
TypePaths have special handling for Self where we can look at the current ctx
for more acurate TypeAlias information if required. We cant do this for Impl
contexts but not for Traits as we might as well fall back to the TypePathProbe.
The other issue was the dyn type comming in because Foo::foo and Foo is a trait
reference we represent this as a dyn type as the root resolved path but then find
the associated impl block for this but we cannot do this when we have resolved to
a Dyn because this is just a representation that we know we are talking about a
trait not because we are actually working with a real Dyn type.
Fixes Rust-GCC#2907
