Preload additional XCB libraries for NVIDIA GPUs

When running on Xwayland, or when using PRIME render offloading on a hybrid GPU
system such as a laptop, the proprietary NVIDIA driver will attempt to load the
following three libraries using dlopen

libxcb-dri3.so
libxcb-present.so
libxcb-sync.so

but chromium's sandboxing of the GPU process will prevent it from doing so.
The driver requires these libraries in order to present rendered content to the
screen, so currently chromium's window will appear completely blank in the
above mentioned situations.

To fix the issue, have chromium preload those libraries when using the
proprietary NVIDIA driver, similarly to how it already does for libxcb-glx.so.
