Fix parsing of shell.homepage
<!-- Please describe your changes on the following line: -->
This should fix the nightly builds crashing, although I don't know how to verify whether my fixes worked since I don't know how to test packaging. Any pointers on how to do that would be highly appreciated.
@paulrouget Please let me know if there are any problems with these changes.

Hold stderr lock when using stdout through Console APIs.
This addresses a longstanding source of intermittent test failures where the stderr and stdout outputs get interleaved and the test harness becomes confused.

Propagate changes in custom properties' computed values to descendants
If ComputedValues.custom_properties differs between the old and new
ComputedValues, indicate that we have to propogate changes to
descendants by setting child_cascade_requirement to
MustCascadeDescendants in cascade_primary.
style::matching::TElement::cascade_primary already calls
accumulate_damage, which eventually calls
ServoRestyleDamage::compute_style_difference in order to check if other
properties' computed values changed. If any of those change, we signal
that we need to propogate changes for inherited properties.
With Properties & Values, some custom properties will not be inherited,
and we will need to revisit this.

Bump serde to 1.0
This is a rebase of #17325 with `[replace]` entries removed, a bunch more dependencies updated, and some more compile fixes. Original work by @Eijebong, thanks a lot!

Fix setting img src before window.onload causing panic
<!-- Please describe your changes on the following line: -->
Setting an image source asynchronously (e.g. using `setTimeout` or in the callback of an `XMLHttpRequest`) before `window.onload` fired would cause a panic due to a preexisting load blocker not being terminated before assigning a new one.
This PR fixes that and adds a test for it.

windows: fix line height handling
hi there!
on windows, this change properly scales a font's line height by its size.
previously, line height was not scaled to the font's size at all, which meant line heights become worse and worse the further you scaled away from the font's design size (in either direction, larger or smaller).
this change makes the `line_gap` ratio and size scale with the font size. i've hand checked that the new computed `line_gap` matches the effective heights in chrome and firefox when `line-height = normal` for a bunch of system fonts. (servo's rendering quality on windows is a different story, though).

i believe this also solves #16476.

Avoid panic when reloading a page with mouse event handlers
This PR fixes issue #16057, by nullifying `topmost_mouse_over_target` inside of the `handle_exit_pipeline_msg` method, in case owner document is the same as the pipeline document that is being destroyed.
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
Testing was done manually, by running `./mach run (-r|-d) "http://localhost:8000/minimal.html" `, where `minimal.html` contains `<div onmouseover="location.reload()" onmouseout="this.clientLeft">hi there</div>`.
