* adds TargetVersion to CrossCompileInfo so that the caller can control the target compilation version (if 0 is passed, the behavior is as before) * adds targetVersion param to SpirvCompilation.CompileCompute/CompileVertexFragment * adds SpirvCompilation.SetDefaultTargetVersionForCrossCompileTarget(CrossCompileTarget, uint version) to allow caller to set global default to avoid having to pass versions into every Compile call

Depending on where you think defaults should live, I can replace this with 0-by-default and let the cpp code handle all non-user-specified defaults.

Could also make this nullable to be clearer with 'unspecified' default.

I didn't look to closely at the details of the various version formats, but I'm not really content with having this dangling off the API like this.
Would you rather see something more strongly typed like struct TargetVersion(uint major, uint minor, uint patch) exposed to callers in the public interface, and then uint GetTargetVersion(Target, TargetVersion) internally? Or target-specific version structs MslVersion(major, minor, patch), GlslVersion(major, minor), or what have you?

Just wanted to chime in and say that veldrid-spirv translation generates shaders with different versions and causes |

the target compilation version (if 0 is passed, the behavior is as
before)
SpirvCompilation.SetDefaultTargetVersionForCrossCompileTarget(CrossCompileTarget,
uint version) to allow caller to set global default to avoid having to
pass versions into every Compile call
While working on the PBR sample, I found that I ran into compilation errors due to the default MSL version being too low. This change allows me to set the MSL version as seen here.
