Each platform stores this in a different place:
- platform_drm uses dri2_surf->gbm_surf->base
- platform_android uses dri2_surf->window
- platform_wayland uses dri2_surf->wl_win
- platform_x11 uses dri2_surf->drawable
- platform_x11_dri3 uses dri3_surf->loader_drawable.drawable
- haiku doesn't even store it!
We need access to the native surface since the specification asks us
to refuse creating a new surface if there's already an EGLSurface
associated with native_surface.
An alternative to this patch would be to create a new
API.GetNativeWindow callback that each platform would have to
implement. While that's something we can definitely do, I prefer
this approach.

Unlike the other platforms, here we aim do guess if the device that we
somewhat arbitrarily picked, is supported or not.
In particular: when a vendor is _not_ requested we loop through all
devices, picking the first one which can create a DRI screen.
When a vendor is requested - we use that and do _not_ fall-back to any
other device.
The former seems a bit fiddly, but considering EGL_EXT_explicit_device and
EGL_MESA_query_renderer are MIA, this is the best we can do for the
moment.
With those (proposed) extensions userspace will be able to create a
separate EGL display for each device, query device details and make the
conscious decision which one to use.

dri2_fallback_swap_interval() currently used to stub out swap interval
support in Android backend does nothing besides returning EGL_FALSE.
This causes at least one known application (Android Snapchat) to fail
due to an unexpected error and my loose interpretation of the EGL 1.5
specification justifies it. Relevant quote below:
The function
EGLBoolean eglSwapInterval(EGLDisplay dpy, EGLint interval);
specifies the minimum number of video frame periods per buffer swap
for the draw surface of the current context, for the current rendering
API. [...]
The parameter interval specifies the minimum number of video frames
that are displayed before a buffer swap will occur. The interval
specified by the function applies to the draw surface bound to the
context that is current on the calling thread. [...] interval is
silently clamped to minimum and maximum implementation dependent
values before being stored; these values are defined by EGLConfig
attributes EGL_MIN_SWAP_INTERVAL and EGL_MAX_SWAP_INTERVAL
respectively.
The default swap interval is 1.
Even though it does not specify the exact behavior if the platform does
not support changing the swap interval, the default assumed state is the
swap interval of 1, which I interpret as a value that eglSwapInterval()
should succeed if called with, even if there is no ability to change the
interval (but there is no change requested). Moreover, since the
behavior is defined to clamp the requested value to minimum and maximum
and at least the default value of 1 must be present in the range, the
implementation might be expected to have a valid range, which in case of
the feature being unsupported, would correspond to {1} and any request
might be expected to be clamped to this value.
Fix this by defaulting dri2_dpy's min_swap_interval, max_swap_interval
and default_swap_interval to 1 in dri2_setup_screen() and let platforms,
which support this functionality set their own values after this
function returns. Thanks to patches merged earlier, we can also remove
the dri2_fallback_swap_interval() completely, as with a singular range
it would not be called anyway.
v2: Remove dri2_fallback_swap_interval() completely thanks to higher
layer already clamping the requested interval and not calling the
driver layer if the clamped value is the same as current.
