why do you need the ExportValue is not Value enough?

Just to make sure it behaves similar to resolving identifier though its not really needed, I just like to keep it in sync with it

Bind the source file as external module only if not already done
Return type of require call is from external module resolution only if it doesn't resolve to local module
Fixes #10931
Note that we cannot fully guarantee that things will work perfectly because by the time we know that require is not a local symbol it is too late since the source file binding has already happened as external module. This is just little better handling in few cases like #10931
