Bevy 3d_scene not working in WebGL2 on windows

[DGriffin91]

From 87e716f to at least main 2e1acb9

• The 2d_shapes example seems to work.
• 3d rendering seems to work for me on MacOS and Linux in the browser (but not for @mockersf in CI).
• Both firefox and chrome are affected.

Bisected the issue back to #23277 (wgpu update for v29)

I can reproduce on linux by setting WGPU_SETTINGS_PRIO=webgl2, even though everything works fine in an actual browser.

The issue seems related to hitting limits on the number of uniforms:

ERROR bevy_render::error_handler: Caught rendering error: Validation Error

Caused by:
  In Device::create_pipeline_layout
    Too many bindings of type UniformBuffers in Stage ShaderStages(FRAGMENT), limit is 11, count was 13. Check the limit `max_uniform_buffers_per_shader_stage` passed to `Adapter::request_device`

wgpu changed the way they calculate the number of bindings in wgu29 (in this PR), which I suspect is why we're only hitting this bug after the update.

I tried in CI and I have crashes on all os/browsers in webgl2:

ERROR  crates/bevy_render/src/error_handler.rs:114  Caught rendering error: Validation Error

Caused by:
  In Device::create_bind_group_layout, label = 'sparse buffer update bind group layout'
    Too many bindings of type StorageBuffers in Stage ShaderStages(COMPUTE), limit is 0, count was 3. Check the limit `max_storage_buffers_per_shader_stage` passed to `Adapter::request_device`
