(The failing NexusPlayer bot is a demo.)
This should make stack traces more useful, turning this sort of thing

GN is now far more capable than our CMake builds.
Time to officially end that experiment.
Reminder how this lands:
1) this CL
2) remove the bots from the masters
3) remove the CMake recipe files
4) remove the CMake files
I'm willing to wait on 4) until we can do GN -> CMake generation, but I don't want the bots to hold us back.

Android API >= 24 implies Vulkan support, so we can have a more useful default here than 'false'. If for some reason you wanted to turn it off, you can still override skia_use_vulkan.
The defined(ndk_api) guards other users of our GN files (Fuchsia) who may not have an ndk_api argument defined in their BUILDCONFIG.gn.

- swap the N5 experiment over to the new GN N5 bot
- cut down on the Windows build duplication: the other two bots
cover x86, x86-64, Release, Debug, _and_ Vulkan already.
- remove the Release-Shared tester: I added this bot to act as a proxy
for the also Shared-build Android bots, but 1) they're fast enough
to no longer need a proxy (see N5 above) and 2) they're no longer
Shared builds. I intend to completely drop support for dm and
nanobench in Shared builds, so this bot will not just drop from the
CQ but completely disappear.

These were intended to prevent GN and GYP Android bots from stomping on
each other. Turns out, they don't, even without this... they're writing
most files to completely separate paths:
- GYP puts most data under $EXTERNAL_STORAGE, generally /sdcard
and its binaries (libdm.so, libnanobench.so, libskia.so, skia_launcher)
in /data/local/tmp;
- GN puts everything under /data/local/tmp, and its binaries (dm, nanobench)
don't overlap GYP's.
So clearing /data/local/tmp was essentially just removing GN's data; GYP's
data file caching was never affected and can't conflict with GN's.

Just to take inventory of which old problems still linger and which are now moot, I've gone out of my way to have this stand alone. All of gn_android_flavor's logic is self contained, without any dependency on the platform_tools scripts.
The tricky bits turn out to be, copying directories containing symlinks---or really any copying involving more than one file---and getting the exit code back from adb shell. Luckily the ADB I've got on my desktop and my Nexus 5x seems to handle this all without the awkward workarounds you see here, so there's hope that One Day Soon the weird parts (basically, anything with inline python) can go away. Once we've got these bots landed green, I'll go see whether the fixes are due to ADB updates, Android updates, or perhaps something else like hardware.
The parts marked TEMPORARY are a nod to the fact that the devices are used by gn_android_flavor and android_flavor both today. It's mostly about not stepping on each other's toes or leaving anything laying around that might confuse each other. The marked parts can go away when bots are either gn_ or non-gn_ but not both.
I have omitted a few steps that may be important, but which are easy independent follow-ups:
- running as root
- locking clocks
- waiting on battery levels
- fancier wait-for-ready than adb wait-for-usb-device
It'd be nice to, e.g., reaffirm that locking clocks helps perf stability, and that we're locking to the best policy. I've tried to keep this CL as trim as possible, leaving any of these vaguely optional steps for later.
As of PS 41 or so, it looks like the trybots are all behaving as expected.
We should expect no new images in Gold. Can we see trybots in Perf yet?
