Bug 1609191 - Disable webrender on devices affected by Adreno shader compilation crash. r=nical

Browse Source 
We encounter frequent crashes in glLinkProgram on some Adreno
devices. This is likely due to a driver bug, but we have been unable
to figure out the exact cause and work around it.

According to the crash data, this bug appears to affect Adreno 505 and
506 devices running Android 9 only. Disable webrender on these devices
in order to avoid the crash.

Depends on D114949
