Move Lisbon to group with London/Dublin and add a few more zones

Lisbon is in WET, but was misplaced along with other cities in CET.
Move it to WET next to London/Dublin. Also add a few European/Asian zones
I missed in the previous CL.

TBR=satorux@hromium.org,nkostylev@chromium.org
BUG=chrome-os-partner:23902
TEST=More zones show up and Lisbon is next to London/Dublin in the tz
selection UI.

cc: Move GPU raster to DirectRasterWorkerPool.

GPU raster belong in its own RasterWorkerPool implementation as
it requires different throttling logic. This moves all GPU raster
to DirectRasterWorkerPool.

gpu: Generate mailboxes on client side

Because mailboxes are now just a random number, we don't need to round-trip to
the gpu process to generate them, which lets us get rid of IPCs, layers, etc.

It also means generating a mailbox can't fail any more (even on a lost context),
so, removing some code paths and associated tests.

I'm adding a debug-only verification to ensure the mailboxes are generated from
the crypto-random function (in debug, we burn a byte to compute a mini XOR-check
as a sentinel for "we went through the Generate function"). It's not a secure
check, but should hit incorrect/unsafe usage.

BUG=None
