Andrew Osmond 128aa4833c Bug 1832354 - Fix null pointer deref after GMP process crash. r=media-playback-reviewers,alwu 
When the GMP process crashes, we may still attempt to deref a null
pointer for the underlying IPDL object in the content process before we
finish shutting down the decoder.

This patch fixes the crash by checking for the null pointer, but also
now caches the plugin type as an enum for use elsewhere in the code.
This minimizes checking the display name of the plugin everywhere to
guess the plugin properties.
