Long overdue upgrade with new versions of LLVM

Notable changes are:

LLVM now require C++17
Deprecation of OpaquePointers

Build to be checked with:

[x] LLVM 16
[x] LLVM 15
[x] LLVM 14
[ ] LLVM 13
[ ] LLVM 12
[ ] LLVM Android NDK (version ?)
[x] LLVM Rust Stable (1.70.0)

Mostly to be tested on:

[x] C (openssl)
[ ] C++ (llvm)
[ ] Rust (alloy-rs/core)
[ ] Android NDK arm64 (openssl)

Test \ Pass	sub	split	fla	bogus	str	all passes together
C (openssl)	~	~	~	~	~	OK
C++ (llvm)	~	~	~	~	~
rust (alloy)	~	~	~	~	~
ndk (openssl)	~	~	~	~	~

OpenSSL 3.1.1 passed

I had to remove LLVMCore thou, we might need to find a portable solution for all thoses link conflicts

As checks with OpenSSL checks are fine, I'm merging this for now.

We will perform more test with a CI or something.
