[Buildroot] [RFC v1 0/6] Vulkan support

A starting point to add some/more Vulkan support to Buildroot.
Targeting towards the RPi Vulkan support (as announced e.g. [1]),
but send as RFC as not (yet) functional:
- did only try to run standalone and/or with Qt EGLFS, but
did not work out as the broadcom vulkan driver is only
functional with X11/XCB
- the Qt Vulkan support seems only be functional with
EGLFS/Vivante and/or X11/XCB
Tested with the following defconfig (and dtoverlay=vc4-kms-v3d-pi4):

- /usr/lib/libVkICD_mock_icd.so: vulkan-tools/moc-ICD
Runtime test done:
- vulkan-tools/moc-ICD (works):
