[Feature] Default options for cmake wraps

[LDAP]

PR https://github.com/mesonbuild/meson/pull/11730 recently added CMake wraps.

Still, meson is missing a way to provide default options to the CMake subproject. This is required quite frequently, for example to disable tests or set the buildtype.

See https://github.com/mesonbuild/meson/pull/11730#issuecomment-1574291316 for context.

Current workaround:

Add the cmake wrap, then use the cmake module as usual:

dep = dependency('name', required: false)
if not dep.found()
    cmake_options = cmake.subproject_options()
    cmake_options.add_cmake_defines(...)
    subp = cmake.subproject('name', options: cmake_options)
    dep = subp.dependency('target'),
