ba4b0e93e3 Add support for number(boolean) and boolean(number) casts in SkSL.
Previously `number(boolean)` casts were converted to a ternary during
IR generation, and `boolean(number)` casts caused an error.

Metal and GLSL should support this cast as written. SPIR-V needed a
little bit of logic to handle converting the boolean to a number via
OpSelect.

ab8ed92a0c Add unit test for casting between float, int and bool.
This actually exposed a latent bug: we don't support bool(1.23) or
bool(1) casts, but these are valid in GLSL:

"to bool: A value equal to 0 or 0.0 becomes false; anything else is
true."

dda1d31623 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.
