Subject: [PATCH] intel: Build float64 shader only for Vulkan

It's only used by anv and it requires glslang, which isn't otherwise
required for building iris.

Fixes: b52e25d3a8e ("anv: rewrite internal shaders using OpenCL")
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/28943>
