1bf9676e87 render/egl: improve modifier support detection 
Support for EXT_image_dma_buf_import_modifiers doesn't necessarily
indicate support for modifiers. For instance, Mesa will advertise
EXT_image_dma_buf_import_modifiers for all drivers. This is a trick
to allow EGL clients to enumerate supported formats (something
EXT_image_dma_buf_import is missing). For more information, see [1].

Add a new wlr_egl.has_modifiers flag which indicates whether
modifiers are supported. It's set to true if any
eglQueryDmaBufModifiersEXT query returned a non-empty list.

Use that flag to figure out whether the buffer modifier should be
passed to the EGL implementation on import.

de0bc78319 render/pixman: advertise MOD_INVALID instead of MOD_LINEAR 
The backends and allocators use INVALID, but the renderer uses
LINEAR. Running a compositor with WLR_RENDERER=pixman results in:

This allows creating a wlr_egl from an already-existing EGL display

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.

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.

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

  v_add_u32     v0, s2, v0                              // 000000000000: 68000002

  v_cvt_f32_i32  v1, v1                                 // 00000000000C: 7E020B01
  v_mul_f32     v1, 0.5, v1                             // 000000000010: 0A0202F0
  v_and_b32     v0, 2, v0                               // 000000000014: 26000082
  v_cvt_f32_i32  v0, v0                                 // 000000000018: 7E000B00
  v_mul_f32     v0, 0.5, v0                             // 00000000001C: 0A0000F0
  v_mov_b32     v2, 0                                   // 000000000020: 7E040280
  v_mov_b32     v3, 1.0                                 // 000000000024: 7E0602F2
  exp           pos0, v1, v0, v2, v3 done               // 000000000028: C40008CF 03020001
  exp           param0, off, off, off, off              // 000000000030: C4000200 00000000
  s_endpgm                                              // 000000000038: BF810000

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)

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.

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).

The half-float formats depend on GL_OES_texture_half_float_linear,

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.

6f19295647 render/egl: initialize wlr_egl with EGL_PLATFORM_DEVICE_EXT 
Uses the EXT_device_query extension to get the EGL device matching the
requested DRM file descriptor. If the extension is not supported or no device
is found, the EGL device will be retrieved using GBM.

Depends on the EGL_EXT_device_enumeration to get the list of EGL devices.
