MediaSourceClientGStreamerMSE: wrap FastMalloc-ed memory into pipeline-bound GstBuffers
https://bugs.webkit.org/show_bug.cgi?id=167928
Reviewed by Xabier Rodriguez-Calvar.
The buffers created in MediaSourceClientGStreamerMSE can be large enough in size
that repetitive allocations can cause larger heap fragmentation in different libc
allocators. To avoid that occurrence, we should simply use FastMalloc to allocate
memory for these buffers.
