Convert several SkSL->GLSL unit tests to golden outputs. The new test files are intended to be identical to the unit tests in every meaningful way. (Comments and formatting are not preserved exactly.) In cases where a unit-test method contained more than one test, multiple test files were created; in these cases, new names were invented to match the apparent intent of each invocation. Followup CLs will continue to migrate additional tests.

Align default values of GrShaderCaps with StandaloneShaderCaps. `fBuiltinFMASupport` is now true on both, and `fUsesPrecisionModifiers` is now false. Other mismatching flags exist, but they are non-trivial to synchronize as they are tied to extension strings. This will help our skslc-based unit tests generate the same results as our C++ unit tests did, but should not affect real-world results as these defaults will all be overwritten in a non-testing scenario. In practice, the `fUsesPrecisionModifiers` change is responsible for all of the diffs below. The other flags did not change the results of any of the currently-ported tests.
