This commit renames "deno_core::InternalModuleLoader" to "ExtModuleLoader" and changes the specifiers used by the modules loaded from this loader to "ext:". "internal:" scheme was really ambiguous and it's more characters than "ext:", which should result in slightly smaller snapshot size. Closes https://github.com/denoland/deno/issues/18020
