Enable C++ 20 standard globally

Description

Note: This is work-in-progress and not ready for review yet. I didn't set it to "draft", as I wanted to test CI to see where things break with C++ 20.

Refs #1201

General Checklist:

Please ensure the following points are checked:

• My code follows the coding style
• I have reviewed file licenses
• I have commented any added functions (in line with Doxygen)
• I have commented any code that could be hard to understand
• My changes do not add any new compiler warnings
• My changes do not add any new validation layer errors or warnings
• I have used existing framework/helper functions where possible
• My changes do not add any regressions
• I have tested every sample to ensure everything runs correctly
• This PR describes the scope and expected impact of the changes I am making

Note: The Samples CI runs a number of checks including:

• I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)
• My changes build on Windows, Linux, macOS and Android. Otherwise I have documented any exceptions

If this PR contains framework changes:

• I did a full batch run using the batch command line argument to make sure all samples still work properly

Sample Checklist

If your PR contains a new or modified sample, these further checks must be carried out in addition to the General Checklist:

• I have tested the sample on at least one compliant Vulkan implementation
• If the sample is vendor-specific, I have tagged it appropriately
• I have stated on what implementation the sample has been tested so that others can test on different implementations and platforms
• Any dependent assets have been merged and published in downstream modules
• For new samples, I have added a paragraph with a summary to the appropriate chapter in the readme of the folder that the sample belongs to e.g. api samples readme
• For new samples, I have added a tutorial README.md file to guide users through what they need to know to implement code using this feature. For example, see conditional_rendering
• For new samples, I have added a link to the Antora navigation so that the sample will be listed at the Vulkan documentation site

Once we merge this, I think we can remove one or two external dependencies (submodules). Right now. printing formatted messages (e.g. errors) is knda complicated and goes through our framework and two externeal dependencies. One of those is "fmt", and it seems that it's functionality is also present in the STL with C++20. So we could get rid of "fmt" and maybe also "spdlog". I don't think we need to have such a complicated setup just for logging.

@jackk18912525: Can you please remove your spam comment and also remove yourself from the reviewers?

A blocker is the HCWPipe third party dependency. I can't get it to compile after updating to C++20, and updating the submodule doesn't help either (esp.a s the library is now differently named). I need help on this from someone from arm, maybe @JoseEmilio-ARM?

@JoseEmilio-ARM : Any update on this? I'm stuck until someone with proper knowledge updates HCWPipe.

@JoseEmilio-ARM : Builds are still failing for me on Android. Seems the HCWStatsProvider needs to be updated to work with C++20:

Any idea on how to fix this?
