Enable SPIR-V disassembly output from skslc. We now have SPIR-V golden outputs for `blend` and `shared` tests. This exposes a handful of SPIR-V limitations for us to address.

Avoid emitting duplicate constant values in SPIR-V. Previously, we had constant-value deduplication, based on the SkSL type of the constant. However, we were still generating redundant constants, because we would emit a separate constant for Float(n) and Half(n), or Int(n) and Short(n), even though we generate the exact same instruction for these constants. We now deduplicate based on the type's number-kind, separating constant literals into three categories: floats, signed ints, and unsigned ints. This better matches our type-handling in getActualType.
