Simon Ser 2e33139ef7 render: introduce WLR_RENDER_DRM_DEVICE
This env var allows to override the DRM node used by the GLES2 and
Vulkan renderers. It's especially useful to select a DRM node when
running with the headless backend.

Simon Ser e4f748c6e9 render/allocator: fallback to renderer DRM FD in autocreate
If the backend doesn't have a DRM FD, fallback to the renderer's.
This accomodates for the situation where the headless backend hasn't
picked a DRM FD in particular, but the renderer has picked one.

Simon Ser bf57825560 render: pick DRM FD in autocreate
If the backend hasn't picked a DRM FD but supports DMA-BUF, pick
an arbitrary render node. This will allow removing the DRM device
selection logic from the headless backend.

With some bit magic, we can get something much nicer:

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

Simon Ser a04cfca4da Remove support for DMA-BUF flags
They are never used in practice, which makes all of our flag

provide a good way to deal with the flags. Let's just fail the
DMA-BUF import when clients provide flags.

nyorain 8e34692250 render/vulkan: add Vulkan renderer
This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.

The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.

Simon Ser 13cdb84ee8 render/allocator: use render node if available in reopen_drm_node
If we aren't trying to create a dumb buffer allocator, and if the
DRM device has a render node (ie, not a split render/display SoC),
then we can use the render node instead of the primary node. This
should allow wlroots to run under seatd when the current user
doesn't have the permission to open primary nodes (logind has a
quirk to allow physically logged in users to open primary nodes).

- gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.

Manuel Stoeckl f5df956c18 render/gles2: add a few 10-bit and FP16 formats
The half-float formats depend on GL_OES_texture_half_float_linear,
not just the GL_OES_texture_half_float extension, because the latter
does not include support for linear magni/minification filters.

The new 2101010 and 16161616F formats are only available on little-
endian builds, since their gl_types are larger than a byte and thus
endianness dependent.

is found, the EGL device will be retrieved using GBM.

This EGL extension has been added in [1]. The upsides are:

- We directly get a render node, instead of having to convert the
  primary node name to a render node name.
- If EGL_DRM_RENDER_NODE_FILE_EXT returns NULL, that means there is
  no render node being used by the driver.
