This uncovered a bug in Metal code generation of `matX *= matY` which is
now fixed. (It was emitting the helper function more than once.)

Previously, our only test was invoking `sin(1)` which is a pretty
ineffective test. Now, we test args and return types for all the basic
scalars/vectors/matrices.

These tests have updated to return green on success, or red on failure.
Some tests were modified slightly to conform to ES2 limitations, or
split into separate ES2 and ES3 parts.

We already had this trick for scalar integers, this extends it to
integer vectors. As with prior work in this area, it would be better to
detect this case and produce an error, but now we at least produce
consistent and well-defined results (rather than undefined signed
integer overflow).

This allows interface blocks in Metal to compile even if
`layout(binding=...)` is not specified. It will also be used in SPIR-V
in the followup CL, when an interface block is automatically synthesized
for top-level uniforms.
This CL also reorganizes the unit tests around uniforms a bit.

This creates a helper function, _entrypoint, which invokes main() and
assigns its result into sk_FragColor. We also make sure to prevent
sk_FragColor from being dead-stripped from the code during IR
generation.
At present this is useful for allowing our SkSL test shaders to compile.

This lets us use descriptive names like `colorRed` and `colorGreen`
instead of `half4(1,0,0,1)` and `half4(0,1,0,1)`. It also lets us use
actual unknown values instead of synthesizing sorta-kinda-unknowns by
calling sqrt.

This allows uniforms to be specified without an explicit `layout(set=N)`
modifier. They will assume a default set value instead.
This turns out to fix a handful of tests in Metal/SPIR-V which were
written with GLSL in mind, or adapted from real generated GLSL code, and
didn't have layout information specified on their uniforms. It will also
make it easier to write SkSL tests using uniforms that can compile
either as a runtime effect or as plain Metal/SPIR-V code.
