Revamp the build system. This achieves several goals: * Less reliance on scripts so we have better portability to Windows (though we still have a ways to go for proper Windows support). Luajit, luarocks, moonscript, and busted are all installed via CMake now. * Trying to make use of pkg-config to get the correct libraries. The latest libuv is still broken in this regard, but we'll at least be in a position to use it. * Allow the use of Ninja or make. The former runs faster in many environments, and automatically makes use of parallel builds. This also allows for system installed dependencies--though not through the Makefile just yet--and adds support for FreeBSD. This also make us build libuv and luajit as static libraries only, since we're only concerned about having static libraries for our bundled dependencies.

build: CMake: remove usage of USE_BUNDLED_X in main project (#10354) The variables are not meant to be defined there really, but only with the third-party project. Using them, e.g. with the following, would actually result in libvterm not being found then: make CMAKE_EXTRA_FLAGS="-DUSE_BUNDLED_LIBVTERM=ON" \ DEPS_CMAKE_FLAGS="-DUSE_BUNDLED=OFF -DUSE_BUNDLED_LIBVTERM=ON" In https://github.com/neovim/neovim/pull/6357 they were renamed to `USE_BUNDLED_X` from `X_USE_BUNDLED`, but the above reasoning applies to the old names, too. Internally `CMAKE_PREFIX_PATH` is used to add the built/bundled third party packages for `find_package`, so there is no reason to e.g. query the values via `load_cache` for example from the third-party project.

CMake: add LibUV_USE_STATIC configuration variable If LibUV_USE_STATIC is set then the static libuv library will be preferred to the shared library. This is useful when building with the bundled libuv but is less useful when building with a system libuv.

cmake: Don't use check_library_exists for Win32 API libraries When building for X86 the CMake check_library_exists always fails to find functions from the Win32 API due to name mangling conventions. The convention for API functions is __stdcall and the CMake test code assumes __cdecl. Since these are libraries from the Windows API we can simply link against the libraries without checking for the functions.
