Allow specifying fx.Module-specific custom loggers with WithLogger

[sywhang]

Currently, passing fx.WithLogger to an fx.Module throws an error like this:

[Fx] ERROR              Failed to start: fx.WithLogger Option should be passed to top-level App, not to fx.Module

This isn't ideal because a library author that exports their app as an fx.Module cannot specify a custom logger whose scope applies to just their Module.

This tracks extending the current implementation of WithLogger option so that it can be passed directly to an fx.Module, such that when it is, it only affects the scope of that Module.
