`GPUCompiler` 0.27 removes `CodeCache` on Julia 1.11

[minecraft2048]

While trying to make StaticCompiler runs on Julia 1.11, I've tried to set GPUCompiler compat to 0.27, and it failed to precompile:

julia> err
PkgPrecompileError: The following 1 direct dependency failed to precompile:

It turns out that GPUCompiler.jl uses Julia internal cache at 1.11: https://github.com/JuliaGPU/GPUCompiler.jl/blob/316668b6d34fc29cf48eb53280e254346ac94e51/src/jlgen.jl#L164 JuliaGPU/GPUCompiler.jl#545

StaticCompiler now works with Julia 1.11 and GPUCompiler v1.5.2 by my last #174
Let me know if anything breaks.

Also working on StaticLLVM.jl to help with IR handling — happy to hear what you'd like it to support!

Thanks!
