Description

Implemented wgpuDeviceCreateShaderModuleTrusted. It only differs from wgpuDeviceCreateShaderModule by a single runtimeChecks parameter, which takes the values of a new bit flag WGPUShaderRuntimeChecks. It isn't specified as a bitfield in wgpu, but it is a struct containing just bools, so I figured a bitmask on the native side is appropriate.

In the implementation, the two methods only differ in a single line, so I extracted a private create_shader_module function that both methods forward to.

This is relevant to #594, I'm considering adding a chain extension instead of this special method.

IIUC you prefer holding off merging?

Not necessarily, my thing will take a while to merge. And if @cwfitzgerald thinks this is a fine way to do it then I'm fine to just go with this.

ok, merging then!
