The xpath resolver is a function provided by the user to resolve
namespace prefixes. Previously, we were ignoring the argument.

For example `div[count(//p)]` should count all `<p>` elements in the
document, not just the ones underneath the `<div>`.
Testing: WPT tests cover this, the fix makes two more test pass.

1. Better handling of namespaces for element and attribute names in XML
mode (read: non-HTML mode)
2. While parsing, pass along context on whether we are in an absolute
(`/`) or descendant (`//`) part of the query, and use it to correctly
enumerate descendants according to where we are in the evaluation of the
AST.
Testing: All 1024 tests in `xml_xpath_tests.xml` (actually
`xml_xpath_runner.html`) pass, as well as some random tests in
`text-html-attributes.html`.
Fixes: #37278
