Matt Woodrow 4e7f9b4789 Bug 1678684 - Initialize DXVA on the media thread, remove the mostly-unused dll blocklist, and the crashguard. r=jya
The main-thread requirements for DXVA appear to have been needed when we initialized a crash guard. We now only run DXVA in the GPU and RDD processes, which don't support crash guards. This removes the main thread dispatch and the crashguard code, and enforces that we're in the GPU/RDD process to init DXVA.

This also removes the DLL blocklist code. This was disabled via pref when in the GPU process, which should be the majority of the time. In rare cases we would have been running DXVA in the RDD process (on older win7 when the GPU process isn't available). In these cases we can just do the same as the GPU process, allowing crashes and recovering from them (and disabling DXVA).
