[Bug]: IsEmpty matcher doesn't work with C-style wide strings

[mondious]

Describe the issue

Compiling a test with the following excerpt fails.
ASSERT_THAT(L"NotEmpty", Not(IsEmpty()));

The overload of IsEmpty for C-style wide strings seems to be missing. The documentation mentions that there should be one.

The testcase does not check for C-style wide string compatibility.

Steps to reproduce the problem

See a minimal example here.

What version of GoogleTest are you using?

Trunk was used in godbolt, so it should be a quite recent version.

What operating system and version are you using?

Windows 11 24H2

What compiler and version are you using?

Reproducible on both gcc-11.4.0 and clang-14.
