Customize eframe persistence file path

[C0D3-M4513R]

Is your feature request related to a problem? Please describe.

When making an app, where you want to allow saving to a custom location (e.g. because you want your users to be able to work on multiple projects at once), you basically have to create a custom eframe::Storage implementation, which for me boils down to just copying the file that eframe::native::FileStorage resides in, removing the profiler macros and making the eframe::native::FileStorage::from_ron_filepath public.

Describe the solution you'd like

just make eframe::native::FileStorage::from_ron_filepath public

Describe alternatives you've considered

just copy the existing implementation

Did #4423 resolve this?

[C0D3-M4513R]

Not really no. I was thinking of being able to load/save from multiple different locations during the lifetime of an app (without re-creating the window). Something like being able to choose a project file to load/save to.

Your pr seems like it fixes the directory location on application start.
