`StylesheetLoader` implements the `StylesheetLoader` trait from Stylo.
This is pretty confusing as the names are the same. This change renames
the Servo version to `ElementStyleSheet` loader so that it's clearer
from reading the code what each of these things are.
Testing: This change just makes a few renames so shouldn't change test
results.

This is part of the future work of implementing LazyDOMString as
outlined in https://github.com/servo/servo/issues/39479.
We use str() method or direct implementations on DOMString for these
methods. We also change some types.

Testing: This is essentially just renaming a method and a type and
should not change functionality.

The existing `assert!(node.is_connected())` is wrong. What it *wants* to
assert is that the style element has an owner, which is either a
Document or a ShadowRoot that the element is a descendant of. However,
if the element is descendant of a ShadowRoot which is itself not
connected to a document then the assertion would fail.
Instead, we use `node.is_in_a_document_tree() ||
node.is_in_a_shadow_tree()`, which more accurately reflects the intent.
Testing: This change adds the test case from
https://github.com/servo/servo/issues/37781 as a crashtest
