Add Random Access Module file names to stack traces

Summary: Adds support to generate stack traces that can be used with source maps that have a `x_facebook_offsets` field. If a file name of a stack frame contains only digits and ends with “.js”, it is included in the trace format generated by `ExceptionsManagerModule`
