add RemoveUnreferencedCodeData option to disable /Zc:inline

[withmorten]

What does this PR do?

This PR adds the option to properly toggle this Visual Studio project build option: https://docs.microsoft.com/en-us/cpp/build/reference/zc-inline-remove-unreferenced-comdat?view=msvc-160

How does this PR change Premake's behavior?

When specifying removeunreferencedcodedata "On" or "Off", <RemoveUnreferencedCodeData>true</RemoveUnreferencedCodeData> or false will be added to the vcxproj in each build config, similar to usefullpaths.

When it is not specified, nothing changes.

Anything else we should know?

By default, Visual Studio assumes this value to be true, when it is not specified. I was annoyed by this (I wanted to replicate compile options from an old project) and decided to add this.

I pretty much just copypasted the usefullpaths behaviour, so I don't expect this to misbehave :)

We've just recently rolled out a new website that allows the documentation to be stored in the main repository. Would it possible to add a documentation page for this new method? Just copy from one of the pages inwebsite/docs and then add it to website/sidebar.js in alpha order. You would need to rebase against the latest changes to see the new site files (which will help getting this merged as well).

Done! I hope I did everything correct, couldn't really preview it. I "guessed" the version it would be available in as alpha 16, hope that was okay :D

Looks great, thanks!
