let's do this sooner rather than later

Are these breaking things?

They're flaking in ways that don't match the other bots.

(afaict, the only difference is the OS version -- K MR1 here vs K MR2 elsewhere)

for example: https://build.chromium.org/p/chromium.linux/builders/Android%20GN/builds/34310

or compare
https://build.chromium.org/p/chromium.linux/builders/Android%20GN?numbuilds=200
vs
https://build.chromium.org/p/chromium.linux/builders/Android%20Tests?numbuilds=200

[Android] Turn down gn-specific Android bots.

All Android bots are now on GN, so there's no longer a reason for these
