Deterministic generator

[t-bltg]

I wanted to update the generator for llvm 14.0.6 for julia 1.9 in #25, however it seems that the generator handles headers in a non-deterministic way. Re-running the generator thus changes the generated signatures every time.

This, probably because julia Sets used in Clang.jl are un-ordered:
https://github.com/JuliaInterop/Clang.jl/blob/c95896f223b88b74e51ceeee65ad74a8108e9474/src/generator/context.jl#L252-L253

Should we fix this ?

Another way to keep the order of headers deterministic is to include all of the headers in https://github.com/Gnimuc/libclangex/blob/master/include/clang-ex/libclangex.h and only pass libclangex.h to Clang.jl's generator without using detect_headers.

List all the headers manually ?
That quite a big list to maintain:

Comparing what I've done in libclangex, this is nothing.

Oh I didn't notice libclangex.h belonging to the libclangex repository sorry, no need to maintain the list outside.
Let's update it then, I will make a PR.
