Make FeatureOverrides/FeatureConfig Parcelable

Implement Parcelable for FeatureOverrides and FeatureConfig. This allows
IGpuService to transmit the data via Binder.

Bug: 372694741
Test: CQ
Flag: com.android.graphics.graphicsenv.flags.feature_overrides
Change-Id: I7b095fcf2b396c8220ff72bed4ee2ef94741b70a
