Update RenderEffectCache capability query

Updated logic to determine if RenderEffectCache
is supported to very both the vendor name as well
as the corresponding driver version.

Bug: 193145089
Test: Added test to EglManagerTests + RenderEffectCapabilityQueryTests
Change-Id: Ia0fd66c40790b94566f495d2c4128c4988d406b6
