    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.

    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++.
