[zlib][build] Remove fdopen #defines in zutil.h.
The latest version of Clang changed what macros it predefines on Apple
targets, causing errors about predefined macros in zlib.

Original commit message:
Define UChar as char16_t
We used to have UChar defined as uint16_t which does not go along
with STL these days if you try to have an std::basic_string<> of it,
as there are no standard std::char_traits<> specialization for uint16_t.
This switches UChar to char16_t where practical, introducing a few
compatibility shims to keep CL size small, as (1) this would likely
have to be back-ported and (2) crdtp extensively uses uint16_t for
wide chars.

Original commit message:
Fix build issue, remove unneeded include uchar.h.
Follow the conversation on:
https://groups.google.com/g/v8-dev/c/nsbshwlmP3c.
The `uchar.h` include is not necessary.
It was added to get the definition of char16_t but that's an intrinsic
type in C++.

Node 20.19.2 currently fails to build from source since Xcode 16.3 (and LLVM Clang 18). This pull request backports three v8 commits that fix the issue:
fdopenis a definition ifTARGET_OS_MACis defined, butfdopenhas never been a definition in the macOS SDK. The latest Clang compiler now definesTARGET_OS_MACglobally, triggering this code and causing a compile error.git-nodedoesn't do backports ofthird_partyrepos so I did this one manuallystd::basic_string<uint16_t>is invalid C++ without a customstd::char_traits. This is now enforced in the latest libc++.All of the above commits are already included in Node 22 and later, hence the 20.x-only PR.
