fix: rename typename U to typename UT to avoid cpprest conflicts

[aminya]

Fixes #4180
Workaround for microsoft/cpprestsdk#1805

[aminya]

The formatting changes are caused by clang-format so that CI doesn't fail

I was using clang-format-18. Using 17 reduces the diff

Thanks for the PR but we shouldn't clutter the code because of poorly written third-party libraries.

That's fair. However, unfortunately, I noticed that OpenAPI cpprest generator also uses U. I don't think it's viable for cpprest to remove the macro at this point. I am going to patch OpenAPI generator to undef U at the end of the headers. A lot of work for a bad name.

That macro is only replacing U() calls, a maybe less invasive change could be to replace them with uniform initializations U{}

@vitaut @edo9300 The actual Diff is much smaller than in the PR:
master...aminya:fmt:type-conficlit

I was still fixing the clang-format version when the PR was closed.

Also, in general using readable typenames instead of single characters is a good idea, however that's another discussion

[edo9300]

Actually, the conflicting code isn't present at all in the current master, so the workaround isn't needed in first place
