[Save/Sync] In-Progress ModConfigXml loading rewrite.

+ Fixed async operations lock for Dispose() pattern in working files.
+ Rewrote StorageService.cs:
--- Now uses ContentPath instead of raw strings where possible.
--- Now throws exceptions for developer errors and critical program states.
+ Rewrote ModConfigService.cs:
--- All functions are now completely async.
+ Removed ConfigProfilesResources completely as they exist in common Config xml files.
+ Somewhat simplified package data and processes.
