Ignore type parameters in macro runtime dependencies

The `macroDependencies` method collects all the definitions that are
required to interpret the contents of the splice (using JVM-reflection).
We do not care about type parameters because those are erased and
the interpreter emulates erased semantics.

Fixes #12498
