Adds support for MSAA to the new renderer. This is done using the new [pipeline specialization](#3031) support to specialize on sample count. This is an alternative implementation to #2541 that cuts out the need for complicated render graph edge management by moving the relevant target information into View entities. This reuses @superdump's clever MSAA bitflag range code from #2541. Note that wgpu currently only supports 1 or 4 samples due to those being the values supported by WebGPU. However they do plan on exposing ways to [enable/query for natively supported sample counts](gfx-rs/wgpu#1832). When this happens we should integrate

Add an example that demonstrates the difference between no MSAA and MSAA 4x. This is also useful for testing panics when resizing the window using MSAA. This is on top of #3042 . Co-authored-by: Carter Anderson <mcanders1@gmail.com>
