android, win: Enable colored test output when available

Browse Source 
Following the discussion at https://crrev.com/c/818125/3//COMMIT_MSG#17,
this sets GTEST_COLOR=yes when running tests on an Android device via
“adb” being driven from a Windows host. This is only done when standard
output is attached to a console and when
ENABLE_VIRTUAL_TERMINAL_PROCESSING is supported (it is on Windows 10).
As usual, colored output can be suppressed by setting GTEST_COLOR=no.

This is only partially tested. Instead of running on-device tests via
adb, I substituted:
  print('\x1b[0;31mred\x1b[32mgreen\x1b[34mblue\x1b[0m')
