For dxvk and vkd3d-proton building on Debian

# For Debian build of dxvk and vkd3d-proton.
#
# 1. To build 64-bit and 32-bit dxvk:
#
# for bitness in 64 32; do project=dxvk bitness=$bitness dxvk_build.sh; done
#
# 2. To build 64-bit and 32-bit vkd3d-proton:
#
# for bitness in 64 32; do project=vkd3d bitness=$bitness dxvk_build.sh; done
#
# 3. To build both:
#
# for project in dxvk vkd3d; do for bitness in 64 32; do project=$project bitness=$bitness dxvk_build.sh; done; done

Note, the script now builds dxvk, vkd3d-proton and d8vk.

Removing d8vk since it's getting into upstream now and can't be built without conflicting with dxvk in the same installation.
