The 2048 surface limit was never wgpu's or the GPU's — it's
downlevel_webgl2_defaults().max_texture_dimension_2d (2048), which
WgpuSettingsPriority::WebGL2 forces. Switch to Functionality: on the WebGL2
(Gl) backend Bevy then adopts the adapter's real limits, which are still
WebGL2-constrained for features/buffers (shaders stay GLES-compatible) but
report the GPU's true max texture dimension (e.g. 16384). The device is
requested with exactly what the adapter offers, so creation can't fail, the
surface is no longer capped, and large viewports (4K) render with no letterbox
and no hardcoded cap.
Removes the resize_constraints cap and the play.html max-width/height caps.
