Project Updates

@XAMPPRocky: Mostly working on investigating bugs in spirv-cross's MSL compiler that we found when trying to integrate rust-gpu with Ark shaders.

@eddyb: Having attribute, instead of wrapper types.
@eddyb: Wants to tackle attributes next.
@eddyb: Essentially model rustc's attribute parsing pass.
@XAMPPRocky: there's also #443 which changes it to be value.
@eddyb: Yeah, that is a starting point, but we need to figure out what we want first.

@Jasper-Bekkers: More progress with bindless
@Jasper-Bekkers: One limitation is that you can't have template parameters to external functions.
@eddyb: I could make a PR to upstream some of that work in rustc.
@Jasper-Bekkers: I worked around it for now, with a custom attribute.
@Jasper-Bekkers: In the builder-methods struct, is it okay to add global ops?
@eddyb: Depends, probably yeah.
@Jasper-Bekkers: Right now I'm adding global types and I'm running into some issues.
@Jasper-Bekkers: So I should create a bunch of SPIR-V types and then assign values to them?
@eddyb: Yep.
@Jasper-Bekkers: Planning on following DXE is doing.

@VZout: MoltenVK 1.1.2, but not much else.
