Update frameworks/base to use newer SkRuntimeEffect::MakeForShader

This enforces stricter rules on the SkSL at effect creation time, and
ensures it's valid as an SkShader (vs. an SkColorFilter). Also updated
some SkSL that was already (or would become) illegal:

- Child shaders must be declared 'uniform', not 'in'
- sampling a child requires coordinates
