Make TrackedRenderPass::set_vertex_buffer aware of slice size (#14916)
# Objective

- Fixes #14841

## Solution

- Compute BufferSlice size manually and use it for comparison in
`TrackedRenderPass`

## Testing

- Gizmo example does not crash with #14721 (without system ordering),
and `slice` computes correct size there

---

## Migration Guide

- `TrackedRenderPass::set_vertex_buffer` function has been modified to
update vertex buffers when the same buffer with the same offset is
provided, but its size has changed. Some existing code may rely on the
previous behavior, which did not update the vertex buffer in this
scenario.
