[Mesa-dev] [PATCH v2 3/7] vulkan/wsi: Generate wayland protocol headers separately from EGL

[Jason Ekstrand]

Previously, we were depending on EGL for generating the headers and
providing the protocol symbols.  However, since neither Vulkan driver
actually wants to link against EGL, this is kind-of pointless.  It also
creates a weird build dependency.
