926a59c3 - [AST][AutoDiff] Provide Lit test case for AutoDiff GenericTypeParamDecl AST verification failure. (#38745)

[AST][AutoDiff] Provide Lit test case for AutoDiff GenericTypeParamDecl AST verification failure. (#38745) Provides reproducer lit test case for AutoDiff implicit auxiliary struct and enum declarations that clone implicit GenericTypeParamDecls from a generic signature into a flat GenericParamList, and lead to a compiler assert about GenericTypeParamDecl depth during merge module operation.
