Robert Findley 69bc821a01 [release-branch.go1.18] cmd/compile/internal/importer: key tparams by Package instead of pkgname
The importer type param index used package name as type parameter key,
causing type parameters to be reused/overwritten if two packages in the
import graph had the same combination of (package name, declaration
name, type parameter name).

Fix this by instead using the *Package in the key.

Note: -G=3 was added to typeparam/issue51836.go, as it is necessary for
1.18 but not for tip.

For #51836
Fixes #51847
