fix(compiler): add PURE annotation to getInheritedFactory calls (#38291)

Browse Source 
Currently the `getInheritedFactory` function is implemented to allow
closure to remove the call if the base factory is unused.  However, this
method does not work with terser.  By adding the PURE annotation,
terser will also be able to remove the call when unused.
