Ian Moody 011b59d595 Bug 1536556 - Replace raw thrown Cr.ERRORs with Components.Exception. r=mossop,remote-protocol-reviewers,marionette-reviewers,whimboo,necko-reviewers,geckoview-reviewers,valentin,agi
Raw Cr.ERROR don't get stack information, same as throwing JS literals instead
of `new Error()`s.

This was done automatically with a new eslint rule that will be introduced in
the next commit.  One instance of a raw Cr.ERROR was not replaced since it is
used in a test that specifically checks the preservation of raw Cr values in
XPCJS.  The rule will be disabled for that instance.
