Add developer option switch to set ANGLE as the default system driver

Browse Source 
This change adds a new developer option switch called
"Enable ANGLE". It defaults to off. User can choose
to toggle it on and off, and the value of the system
property "persist.graphics.egl" is changed accordingly:

switch off: persist.graphics.egl=""
switch on: persist.graphics.egl="angle"

When user toggles the switch, a reboot window is
popped up asking user to reboot now to make the change
takes effect. If user chooses to cancel the reboot,
the switch is toggled back. This enforces that a reboot
is required whenever the "persis.graphics.egl" value
changes.

Upon reboot, we will load either ANGLE or native
GLES driver as the system driver, based on the value of
"persist.graphics.egl".

The switch is disabled if ANGLE is not installed
in /vendor partition. We use the system property
"ro.gfx.angle.supported" as an indicator. We set the
two conditions together in angle.mk file. Any device
mk file that inherits angle.mk file will result in
ANGLE libs installed in /vendor and "ro.gfx.angle.supported"
set to true.
