While working on an unrelated test, I accidentally triggered a bug in
Metal code generation. Our struct-equality helper functions did not
properly handle vector fields. Wrapping each comparison in `all(...)`
fixes the problem. (all() on a scalar is allowed and does nothing.)
Our struct comparison tests now include a vector and a matrix.

This is a reland of 830c69ca66
Original change's description:
> Implement operator== and != for Metal structs and arrays.
>
> GLSL/SkSL assumes that == and != on struct/array types should work.
> We need to emit equality and inequality operators whenever we find code
> that compares a struct or array.
>
> Structs and arrays can be arbitrarily nested, and either type can
> contain a matrix. All of these things need custom equality operators in
> Metal. Therefore, we need to recursively generate comparison operators
> when any of these types are encountered.
>
> For arrays we get lucky, and we can cover all possible array types and
> sizes with a single templated operator== method. Structs and matrices
> have no such luck, and are generated separately on a per-type basis.
>
> For each of these types, operator== is implemented as an equality check
> on each field, and operator!= is implemented in terms of operator==.
> Equality and inequality are always emitted together. (Previously, matrix
> equality and inequality were emitted and implemented independently, but
> this is no longer the case.)

This is allowed in OpenGL ES2, and its absence in SkSL has been a pain
point for new users adopting Runtime Effects.

OpenGL ES2 allows structs to be compared: http://screen/6KnX4ZfkdLtqDWv
This already worked in GLSL, Metal and SkVM.

This is a known deficiency of runtime effects, next step is to fix how
they manage function signatures to solve the problem.
