perf(bitmap): recycle

[alperozturk96]

Implements: #17640

Changes

• After using bitmaps recycles them
• Implements ComponentCallbacks2 for FileThumbnailGenerator.kt so that we can do cleanup job.
• Uses ThumbnailUtils.OPTIONS_RECYCLE_INPUT so that we can recycle the input in extractThumbnail(Bitmap,int,int,int)
• Moves Bitmap related logics to BitmapUtils.kt instead having them in ThumbnailCacheManager.java

How to test?

• Check avatar generation in the file list and file detail
• Check media and album tabs
• Check previews in file listing
• Check previews in unified search
