[client] resources: clean up icon handling
...
This commit turns the icon handling into using a macro so we don't need to do
weird conversions from unsigned long (needed by X11) to uint32_t (needed by
Wayland).
Also simplified the error handling path on Wayland.

Generate the EDID once during adapter initialization and update only the

Changing the EDID during a monitor replug causes Windows to identify it
as a different monitor, losing the existing display configuration.
Reusing the original EDID preserves the monitor identity while still
allowing dynamic modes to be advertised through IddCx.

Build the active filter chain only when its configuration changes,
including filter settings or order, input format, dimensions, output

Unchanged frames now execute only the cached active filters, avoiding
repeated setup, preparation, and output-resolution queries.
Reconfiguration forces a full-frame pass to prevent stale intermediate
framebuffer contents.
Also refresh CAS and FSR uniforms when loading presets and move
downscale pass selection out of the per-frame path.

Track context-local GL bindings to avoid redundant program, framebuffer,
buffer, texture, sampler, viewport, blend, and scissor state changes.
Invalidate the cache across context switches, ImGui rendering, and
shared object changes. Preserve CPU-backed texture upload correctness by
explicitly clearing pixel unpack buffer bindings where required.
This reduces hot-path driver overhead without adding waits or GPU
synchronization.

[client] egl: remove blocking waits from frame submission
...
Track PBO fences per upload slot and wait only when a slot is reused,
allowing rendering to proceed without a CPU stall. Use GPU-side waits
for cross-context DMABUF synchronization.
Also propagate KVMFR write-completion failures so incomplete
shared-memory frames are never submitted, while retaining incremental
damage-copy waits to avoid added latency.

[client] egl: add cached uniforms and multipass effects
...
Replace the per-frame uniform list with stable, name-cached handles that
retain their values across shader recompilation. Track dirty uniforms so
only changed values are uploaded, reducing redundant GL calls and buffer
management.
Add a reusable effect-pass pipeline with per-pass shaders, samplers,
formats, resolutions, and intermediate render targets. This makes
external effects easier to integrate and supports arbitrary multipass
chains.
Migrate the desktop, cursor, damage, 24-bit, downscale, CAS, and FSR
rendering paths to the new APIs. Also ensure framebuffer objects are
released correctly.
