Fix windows builds

[alphastrata]

Windows by default will use the msvc linker, which maxes out on 2^16-1 symbols, which the ash and wgpu examples in debug mode easily exceed.

Solution: rust-lld.exe, which should be available already as it's in the llvm-tools that the rust-toolchain.toml will be ensuring is installed anyway.

Can confirm that the ash and wgpu examples fail to build on windows, when build in debug mode (eg, --release works on master), and this PR fixes that.

CI only checks the examples and builds the example shaders, never actually fully builds the examples. @LegNeato should we cahnge our CI to not run into this again?

(I didn't actually know you could use rust's lld linker for windows as well)

I will confirm this shortly.

I can't take the credit, I found it some years back in the Bevy community.

@Firestar99 I think we had a other issue around here to make CI do debug as well. Only doing ---release has caused issues in the past: #40

both ash and wgpu builds (debug) fail without the rust-lld fix, they both wail with LINK : fatal error LNK1189: library limit of 65535 objects exceeded␍ errors. So I think this is a good fix. @Firestar99
