Implement Animate trait for SVGPathData.
The basic idea is: we normalize |this| and |other| svg paths, and then
do interpolation on the normalized svg paths. The normalization is to
convert relative coordinates into absolute coordinates, so we could do
real number interpolation on each path command directly.
In this patch, we also make |clip-path:path()| animatable.

Add a new control message to drop remove worklets.
Implement `Drop` for `Worklet` and get the worklet thread pool. Use that
pool to send `ExitWorklet` to all the threads with the id of the
`Worklet` that it's dropping.
Some drive-by perf improvements on the WebGL stack
This avoids a bunch of pointless buffer and texture copies, but is far from eliminating all which could be eliminated.

There is no need to pass the target to that buffer method, given the buffer
has been retrieved by looking up the one bound to that target in the context.
Read file URL in chunks
<!-- Please describe your changes on the following line: -->
This is a very straightforward PR: essentially, I replaced a `read_to_end` call that occurs when processing a file URL fetch with a loop that reads the file in chunks (with a `FILE_CHUNK_SIZE` constant that specifies the chunk size, which I've put at 32KB), and then calls `target.process_response_chunk` to process the chunk. The chunk is then appended to the fetch result, and once the end of the file is reached, the result is returned.
