Add AlphaMask2d phase (#14724) 
# Objective

- Bevy now supports an opaque phase for mesh2d, but it's very common for
2d textures to have a transparent alpha channel.

## Solution

- Add an alpha mask phase identical to the one in 3d. It will do the
alpha masking in the shader before drawing the mesh.
- Uses the BinnedRenderPhase
- Since it's an opaque draw it also correctly writes to depth

## Testing

- Tested the mes2d_alpha_mode example and the bevymark example with
alpha mask mode enabled

---

## Showcase


![image](https://github.com/user-attachments/assets/9e5e4561-d0a7-4aa3-b049-d4b1247d5ed4)

The white logo on the right is rendered with alpha mask enabled.

Running the bevymark example I can get 65fps for 120k mesh2d all using
alpha mask.

## Notes

This is one more step for mesh2d improvements
