Upgrade to Bevy 0.14

[zhaop]

This PR allows transform-gizmo-bevy to be used with Bevy 0.14. Closes #66.

Before we merge this PR, we should probably take this opportunity to get #68 merged first (upgrade all the dependencies' versions at once).

---

Concretely, this implements the following migration steps:

• Upgrade bevy & its subcrates to 0.14
• Upgrade required rustc to 1.79.0 (from 1.77.0) as required by Bevy
• Disentangle bevy_utils/bevy_core's reexported dependencies bevyengine/bevy#12313 : Add bytemuck & util as dependencies
• Normalise matrix naming bevyengine/bevy#13489 : Rename camera.projection_matrix to .clip_from_view
• Refactor App and SubApp internals for better separation bevyengine/bevy#9202 : Match get_sub_app_mut as an Option
• Consolidate Render(Ui)Materials(2d) into RenderAssets bevyengine/bevy#12827 : Impl RenderAssets for GizmoBuffers instead of GizmoDrawData
• Implement GPU frustum culling. bevyengine/bevy#12889 : Rename Transparent3d dynamic_offset to extra_index
• Improve performance by binning together opaque items instead of sorting them. bevyengine/bevy#12453 & Make render phases render world resources instead of components. bevyengine/bevy#13277 : Use ViewSortedRenderPhases instead of RenderPhase
• Migrate from LegacyColor to bevy_color::Color bevyengine/bevy#12163 : Use RED, LIME, BLUE from bevy::color::palettes::css & Into
