This is a syntax cleanup, not needed for running libc++'s tests with
MSVC's STL.
While changing
`libcxx/test/std/input.output/filesystems/fs.enum/enum.path.format.pass.cpp`
in #74965, I noticed that libc++'s tests almost always use the
special-purpose macros for "this is a libc++-specific `static_assert`
etc." defined by:
b85f1f9b18/libcxx/test/support/test_macros.h (L240-L253)
However, there were a very small number of occurrences that were using
the general-purpose `LIBCPP_ONLY` macro when they could have been using
the special-purpose macros. I believe that they should be cleaned up, to
make it easier to search for usage, and to make it clearer when the full
power of `LIBCPP_ONLY` is necessary.
This is a pure regex replacement from
`LIBCPP_ONLY\((assert|static_assert|ASSERT_NOEXCEPT|ASSERT_NOT_NOEXCEPT)\((.*)\)\);`
to `LIBCPP_\U$1($2);` using the power of [VSCode's case changing in
regex
replace](https://code.visualstudio.com/docs/editor/codebasics#_case-changing-in-regex-replace).
To avoid merge conflicts, this isn't changing the line in
`libcxx/test/std/input.output/filesystems/fs.enum/enum.path.format.pass.cpp`
that #74965 is already changing to use `LIBCPP_STATIC_ASSERT`.
