Fix a bunch of clippy lints
This fixes about 130 clippy lints. Let me know if i should split up the commit.
I wasn't sure about some of the changes, especially map_or instead of map(...).unwrap_or(...) and if let instead of single arm match were not always a strict improvement in my opinion, but i'll leave that decision to the reviewer :)
There are about 150 lints left which i thought were clippy bugs or i didn't know how to fix.

Support empty strings as the repeat argument (CreatePattern)
According to the third step in the specification [1], createPattern
should let the repetition argument be "repeat" when it is the empty
string.
The code in CanvasRenderingContext2D::CreatePattern did not implement
this step and instead threw a SyntaxError exception when an empty
string was supplied as the repetition argument.
Fixes#9079.

This should make it somewhat easier to experiment with alternative
representations in the future. To reduce churn, this commit leaves the String
field public, though.
Also, this will allow us to use the default String type to represent the IDL
USVString type, which explicitly forbids unpaired surrogates, ans as such is
a better match to the Rust String type.
Basically, instead of trying to check for specific kinds of statements,
just check the types of all local variables.
Also included are some commented-out proposals for some slightly more
aggressive lints which might be useful (but trigger a little too
frequently at the moment).
add (un)premultiply tables for canvas {Get,Put}ImageData operations
Pretty straightforward use of lookup tables to replace a bunch of expensive float operations.

This trait is used to hold onto the downcast and upcast functions of all
castable IDL interfaces. A castable IDL interface is one which either derives
from or is derived by other interfaces.
The deriving relation is represented by implementations of marker trait
DerivedFrom<T: Castable> generated in InheritTypes.

This commit implements WebGL's:
* cullFace
* frontFace
* enable
* disable
* depthMask
* colorMask
* clearDepth
* clearStencil
* depthFunc
* depthRange
* hint
* lineWidth
* pixelStorei
* polygonOffset
* texParameteri
* texParameterf
* texImage2D (partially)
It inlines a lot of OpenGL calls to keep the file
`components/canvas/webgl_paint_task.rs` as small as possible while
keeping readability.
It also improves error detection on previous calls, and sets node damage
on the canvas in the drawing calls.
It adds a `TexImage2D` reftest, even though it's not enabled because:
* WebGL paints the image when it loads (asynchronously), so the reftest doesn't wait for it and it finishes early
* If we change the source for the base64 src of the image it works as expected in non-headless mode, but the test harness locks
