As `ImFontLocked` utilizes a reference counter, changed it to a class so that at worst case we still got the destructor to decrease the reference count.
`BuildFontsImmediately` and `BuildFontsAsync` set `BuildTask` to completion at different point of build process, and changed the code to make it consistent that `BuildTask` is set to completion after `PromoteBuiltData` returns.
`PostPromotion` is removed, as `IFontHandle.ImFontChanged` now does the job. It also removes the possibility that resources may get disposed while post promotion callback is in progress.
* `IFontHandle.ImFontChanged` is now called with a locked instance of the font.
* `IFontHandle.ImFontLocked`: Added `NewRef` to increase reference count.
These changes are done to ensure that `IFontHandle.Lock` will be guaranteed to obtain a fully built font that will not be modified any further (unless `PostPromotion` is being used for modifying fonts, which should not be done by clients.)
* Moved `CopyGlyphsAcrossFonts` and `BuildLookupTable` from `PostPromotion` to `PostBuild` build toolkit.
* `IFontAtlasBuildToolkit`: Added `GetFont` to enable retrieving font corresponding to a handle being built.
* `InterfaceManager`: Use `OnPostBuild` for copying glyphs from Mono to Default.
* `FontAtlasBuildStep`:
* Removed `Invalid` to prevent an unnecessary switch-case warnings.
* Added contracts on when `IFontAtlas.BuildStepChanged` will be called.
