Detect and report numeric overflows in the SkSL parser. Previously, some types of overflow were detected, but most would assert or silently generate invalid code. Now, the parser will properly report an error if it encounters any integer that exceeds UINT_MAX or any float that exceeds FLT_MAX. This fixes test OverflowUintLiteral.sksl. Added a test for floats as well, OverflowFloatLiteral.sksl. OverflowIntLiteral.sksl does not fail yet, because its values are larger than INT_MAX, not UINT_MAX. These are legal from the perspective of the parser. This must be caught later at IR generation time.
