Add enable_automation build switch.

Add enable_automation build switch.

It's only disabled on Android to exclude automation from Android build.
enable_automation=0 still doesn't work on platforms other than Android.

@jam, does the way to exclude automation look good to you? I tried to minimize
the locations to added #if defined(ENABLE_AUTOMATION). The test targets
depending on automation (e.g. ui_tests, performance_ui_tests, etc.) are not
excluded on platforms except Android. Do you think we should make
enable_automation=0 work on other platforms too?

nit: move this  to line 1723 and then you can have one ifdef here instead of two

Done (with if (process_startup) also merged into the first condition)
