Use local XCB header copies

This change adds copies of the XCB and XCB Shm 1.2 client API headers
to our repository's include directory. This way the libx11-xcb-dev and
libxcb-shm0-dev packages are not required to build WSI support for XCB,
which is now enabled by default.

Note that we already dynamically look for the XCB shared library before
actually exposing the VK_KHR_xcb_surface extension.

Only the CMake build for desktop Linux is affected. The implementation
of the extension is very small, but if XCB support is not needed at all
the SWIFTSHADER_BUILD_WSI_XCB CMake variable can be set to FALSE.
