GLSL: set integers to precision highp.
In GLSL fragment shaders, int and uint default to mediump, which has
implementation-defined precision. This means that a push constant block
shared between vertex and fragment shader containing an integer type
will error at link time.
WGSL mandates that i32 and i32 are 32-bit (natch), so force fragment
shader integers to highp, as we were already doing for floats. highp is guaranteed to be 32-bit in GLSL.
