build: cmake: unsupported compilers cleanup

[spalicki]

Build files and documentation cleanup to remove dependencies and hacks for GCC < 8 and Clang < 11.

The main driver for this change is cleaning up old workarounds for compiler bugs from codebase and compiler version checks from the build system. The change is driven by RHEL 7 reaching end of support and new versions allow oneDNN to build on RHEL 8 out of the box.

AArch64 validation is outdated, it is now on ubuntu 22.04 with gcc-10, gcc-13 and clang-17

MacOS-14 is also run in the CI with AppleClang 15 (though the default compiler is determined by GitHub runner images).

Also, can you rebase, the CI should be fixed now.

@theComputeKid I have updated the README entries for AArch64 based on #2294 and what you posted here.

[theComputeKid]

Is this a draft or would you like me to review?

[theComputeKid]

AArch64 looks good to me. I'm always tweaking CI (Arm runners are still new) so if anything changes, I'll change it here too.

@dmitry-gorokhov, @ilya-lavrenov, @vladimir-paramuzov I looked through OpenVINO build documentation, and it specifies that the lowest supported OS is Ubuntu 18.04 and GCC 7.5.0. Release documentation does not have these dependencies and starts at Ubuntu 20.04 (and I assume GCC 8.5.0) but at the same time shows CentOS 7. Since we want to move past GCC 7, can you tell us which documentation (and OS/compiler pair) is correct?

[ilya-lavrenov]

Ubuntu 20.04 is minimal
CentOS 7 is supported with non default compiler (we use manylinux docker image with gcc-10)
We also support RHEL 8.4 with gcc 8.5

There are some outdated compiler version checks in the implementation:

• src/common/compiler_workarounds.hpp
• src/cpu/x64/jit_uni_xf16_sum.cpp#L439
• src/common/dnnl_thread.hpp#L197

I would not touch third party components like Xbyak, spdlog and gtest.
