Fix Metal memory management and the `canvas_metal_minimal`, `canvas_nanovg`,

and `macos_app` examples.
`winit` does not create an autorelease pool, so the Metal backend had not taken
the presence of one into account. Now the Metal backend creates and flushes
autorelease pools as necessary.

Faster sorting strategy, remove SortedVector

point_queue is only sorted by y coordinate to coordinate
work to one strip at a time. This is more efficiently handled
by punting later work into a next_point_queue,

active_edges is only sorted by x coordinate for the tile-by-tile
work in process_old_active_edges. It is much more efficient
to sort once inside that function.

Add a compute shader path, optimize GPU memory management, and switch from SDL
...
to `surfman`.
This is a large commit; explanations of each change follow.
This adds an optional compute shader path, off by default, for rendering fills
to alpha masks. It usually does not improve performance at present, but it
provides a good baseline for further optimizations. Later improvements will
likely aim to avoid writes to the mask texture entirely. Supporting
infrastructure for compute shader has been added to `pathfinder_gpu` for the
OpenGL and Metal backends.
The Metal backend has been optimized to avoid unneccessary buffer allocations
and reflection. As part of this, argument buffers have been removed, as the
current SPIRV-Cross compiler no longer requires them.
The GPU renderer has been improved to avoid stalls. Now, separate buffers are
allocated for each fill batch and for each frame. This can be extended in the
future to allow for separate buffers for tile draw operations as well.
SDL usage has been removed in favor of the native Rust `surfman` and `winit`.
Because `surfman` allows for selection of the integrated GPU on multi-GPU
system, it is chosen by default. The demo supports a new
`--high-performance-gpu` option to opt into the discrete GPU.

Replace layers with render targets, which can be used as patterns.
...
This allows us to efficiently handle a lot of workloads that require multiple
HTML canvases, without CPU readback. For example, you can render paths to a
render target, then turn that render target into a repeating pattern that you
fill other paths with. Or you can render paths to a render target and then
composite that render target as a whole with a blend mode.
This introduces a new `DrawRenderTarget` render command that blits a render
target without any paths involved. This is basically just a hack that works
around the fact that our tiled renderer doesn't yet support effects that widen
the ink region (i.e. blurs). It can be removed once we have that support.
