Revert 155122 - Code to collect issue 97285 debugging info for crash reports.

[TPM is suspicious of Windows renderer crash rate.  Seems impossible,
but who knows?]

It is useful to record breakpad keys for debugging, which is not
applicable to multi-process bugs.  This adds infrastructure to allow
collection of information across processes.

Also, fix so that GetPluginChannelHost() can successfully fail without
crashing.

BUG=97285,141055
