In #42492 the template type checker became capable of replicating a wider range of generic type parameters for use in template type-check files. Any literal types within a type parameter would however emit invalid code, as TypeScript was emitting the literals using the text as extracted from the template type-check file instead of the original source file where the type node was taken from. This commit works around the issue by cloning any literal types and marking them as synthetic, signalling to TypeScript that the literal text has to be extracted from the node itself instead from the source file. This commit also excludes `import()` type nodes from being supported, as their module specifier may potentially need to be rewritten. Fixes #42667 PR Close #42761
