Fix#14497: WeakMediaQueryListVec assumes its contents are still alive
<!-- Please describe your changes on the following line: -->
First time contributor here. Noticed this issue is easily solved, so I did it. I am very unsure about how things work here: Is a test needed? What should it look like? Should the "unwrap" be avoided (making bigger changes to the code)?

Per https://html.spec.whatwg.org/multipage/embedded-content.html#dom-img-width:
The IDL attributes width and height must return the rendered width and
height of the image, in CSS pixels, if the image is being rendered, and is
being rendered to a visual medium; or else the density-corrected intrinsic
width and height of the image, in CSS pixels, if the image has intrinsic
dimensions and is available but not being rendered to a visual medium; or
else 0, if the image is not available or does not have intrinsic dimensions.
Use Box<CalcLengthOrPercentage> in specified values to avoid bloating inline sizes
For #15061
CalcLOP is a large struct, and gets used quite often. While #15063 reduces its size a bit,
it will still be much larger than any of the other variants in the `specified::Length*` types,
so it will still bloat sizes, especially for specified values that contain many lengths.
This change boxes it in the length types, so that it just takes one word.

Do not use the script element's line number for external scripts.
This was yielding incorrect line numbers when looking at JS backtraces in gdb.

Make WebIDL callbacks permanently rooted
This replicates the same model that Promise uses right now, because it requires less thinking than coming up with something else.

Use the newly stored line as the starting line number when
evaluating JS. This ensures that inline scripts will report
errors with meaningful line numbers.
