Added isolates for remaining tests on GPU bots.

These represent the non-Telemetry tests currently running on these bots.

Tested locally on Linux. Will test on other platforms after the initial
commit and update the isolates as necessary.

Squelch context menus on the OSX App List when both buttons are pressed.

The apps grid uses [NSView menuForEvent:..] for its menus, so needs to
check the button state explicitly to match the behaviour of [NSButton
menu] (which isn't used, e.g., because the NSButton doesn't fill the
grid cell).

This CL adds a check to suppress the menu when the button is in the
"lit" state, which occurs when the button is being held down.

TEST=Hold the left, then the right, mouse buttons over a app launcher
item. A menu shouldn't appear. Releasing the left button (without moving
the mouse cursor) will launch the item.

Make aura_demo work on Mac

Fix a few instances where !Windows is assumed to be Linux.

Chang many instances of !USE_GTK_MESSAGE_PUMP &&
!OS_MACOSX && !OS_ANDROID to just USE_AURA (they are
equivalent now).

Add a very minimal RootWindowHostMac.

Of note is that building with Aura requires running
"gyp_chromium --no-circular-check" (the circular
check is only enabled on Mac, and doesn't work with
Aura).

Also note that the demo does not work properly unless BGRA
support is disabled (in FeatureInfo::InitializeBasicState these
extensions can be disabled).
