Subject: define Command::IsMediaKey on mac

the definition is copied from //chrome/common/extensions/command.cc,
which also defines a bunch of other stuff that depends on extensions.
since we only need IsMediaKey, and we don't want the extensions stuff
(and aren't compiling command.cc), it's safe to duplicate the
definition. A candidate for upstreaming would be to move the IsMediaKey
function into //ui.

Also apply electron/electron@0f67b1866a9f00b852370e721affa4efda623f3a
and electron/electron@d2368d2d3b3de9eec4cc32b6aaf035cc89921bf1 as
patches.
