features: frontload feature overrides
This allows us to have features that depend on the state of other
features more reliably.
For example, let's say you have two features:
ANGLE_FEATURE_CONDITION(&mFeatures, allowX, (benefitsFromX || isSpecificHardware) && !isBadHardware);
ANGLE_FEATURE_CONDITION(&mFeatures, supportsX, hardware.featureXSupported && mFeatures.allowX.enabled);
Before this change, if you overrode allowX, the override would be
applied too late for the supportsX test.
This also helps with disabling dependent features via overrides. For
example, if you disable "supportsRenderpass2", it will also disable
features depending on it, such as "supportsDepthStencilResolve" and
"supportsFragmentShadingRate".
By frontloading the feature overrides, we can have cross-dependencies
between "feature supported on this platform" and "allow this feature by
policy".
