### Compilation failed:

error: 1: 'in' variables cannot use initializer expressions
1 error
Report an SkSL error if an `in` var has an initializer expression. This resolves the fuzzer error, as the program will fail compilation before reaching the SPIR-V translation stage at all.

Add unit test for fuzzer-detected error with in vars. `in` vars shouldn't support initializer expressions at all. The fuzzer noticed that dead-stripping interacts poorly with `in` var initializer expressions, which makes sense because it's an unsupported and untested path. In a followup CL, lines 1 and 3 will both become errors.

Force global initializers to be constant expressions Prevents us from accepting code that can't be correctly transformed to GLSL, like: uniform float x; float y = x; (Previously, writing code like that in a runtime effect would effectively produce the exact same code all the way through to GLSL, and the driver would fail to compile it).
