We define the standalone types for using derive macro easily and overriding
the behaviors of this traits. This could avoid defining the general
behavior of booleans.

Here, we change the animation type of offset-path as ComputedValue, so
we could do animation on it. Also enable the wpt for offset-path
interpolation. In test_transition_per_property.html, we add some basic tests
ifor offset-path.
ToAnimatedZero for PathCommand will be dropped later.
Because the animations of arcs with mismatched flags are fallen back to
discrete animations, the result of getComputedValue is not normalized in this
case. This makes some wpt failed even though the progress is 100%.

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.

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.

Looks like this produces sensible results for interpolation with 0, though I'm
not really convinced about the results from, let's say, 1px to 2000px in the
attached test-case, I would've expected a linear interpolation from that to go
through normal length interpolation.
css-transforms-1 says:

Which is what we do... I was going to file a spec issue but turns out that it's
already addressed in css-transforms-2:
https://drafts.csswg.org/css-transforms-2/#interpolation-of-transform-functions
Which says:
> The transform functions <matrix()>, matrix3d() and perspective() get
> converted into 4x4 matrices first and interpolated as defined in section
> Interpolation of Matrices afterwards.

This also removes one of my FIXMEs from when I was looking at this code.
We don't seem to have a pre-existing test for this feature, sigh. I'll try to
write one if I have cycles for it...
Note that it not applying XBL rules is a feature, given the current state of
affairs. Video controls and such are right now unusable with no styles enabled.
