[GTK][WPE][Skia] Allow cross-thread transfer of accelerated ImageBitmap
https://bugs.webkit.org/show_bug.cgi?id=283704
Reviewed by Nikolas Zimmermann and Carlos Garcia Campos.
When using skia, transferring ownership of accelerated ImageBitmaps causes
GrDirectContext mismatches
that lead to problems with reading pixels, drawing etc. So far, to fix such
problems, accelerated
ImageBitmaps were decelerated before transferring.
This change improves the above fix and allows the transfer of accelerated
ImageBitmaps. To make such
ImageBitmaps working correctly, however, this change utilizes the code that
re-wraps ImageBuffer with
a proper GrDirectContext. To make that operation safe, the fences are used.
