Update Steam Audio to version 4.5.3

Boolean being U4 didn't really work on my side while default U1 or even Bool worked just fine so I've decided to include that in the diff. Other than that it's just a straight up phonon/cppcodegen update.

Newest versions of CppAst.CodeGen use net8 with nint pointers which is quite a breaking change (would require the lib to target net8 instead of netstandard2.0) so it's not included here

Thank you, this is good. However, this is a pretty old & unkempt repo that contains a few decisions that I nowadays consider to be mistakes.

I have now pushed a compact history rewrite on dev that:

• Gets rid of natives and headers distributed in the tree, in favor of manual installation of them. Otherwise, non-shallow clones of the repo will quickly grow to gigabytes, as Phonon's binaries are very large. A submodule with reliable C++ building may be better in the future, now that we've been blessed with the opensourcing.
• Splits natives out of the main NuGet package into SteamAudio.NET.Natives. People could already avoid 'consuming' natives out of packages, but I believe that doesn't shrink the ~130MB download?
• Prettifies some files.

..& will now force-push a rebase here. Backup your local copies if necessary.

Cool, thanks to GitHub for closing this. I should've pushed first & changed base after. I've pushed the rebase on my remote as pr/update-phonon, please recreate the PR from a copy of it.

Unfortunaly I can't haha. I also forgot to update Shared.targets and now can't do it since this isn't my branch now

[Mirsario]

That's why I said 'from a copy of it', take my edit of your branch to your fork/remote (or just run your own rebase, a matter of removing some files). My apologies for these shenanigans. The Shared.targets file was added in a new commit, you didn't forget it.
