* Align XML parsing and libraries with Python 3.15
Retain the existing XML backend accounting changes and their explicit registry publication limitation. Preserve canonical XML tests and existing RustPython guards, including multiline marker explanations through update_lib.

* Retire proven XML guards and sync canonical consumers

* Rebase vendored xml onto 1.4.0
Replace the vendored crate sources with the published xml 1.4.0 archive
and reapply the amplification accounting patch on top of it. The two
lexer hunks that conflicted with the new line-ending normalization are
merged into the 1.4.0 read loop. The patch no longer normalizes CR in
entity values or collapses CRLF in attribute values, because the 1.4.0
lexer and attribute reader already do so.
Update the checksums, recorded upstream commit, archive hash and
provenance notes, and require version 1.4 for the path dependency.

* Remove stale SAX external resolver expected failure
Linux and macOS canonical CI both demonstrate that the existing
unsupported-scheme resolver test passes. Retire only its expected-failure
decorator through update_lib, preserving its canonical assertions.
This does not implement external DTD parsing.
AI assistance: dot diagnosed CI, migrated the marker, and reviewed the
source delta and normal-hook validation; the model version is not exposed.

* Let xml.sax initialize pyexpat-backed parsers
RustPython already exposes an Expat-like XML parser, but xml.sax expects a few setup APIs before parsing. Add compatible parser setup methods and constants without pretending to implement full Expat external entity behavior.
Constraint: Lib/test changes only remove expectedFailure markers for tests that now pass; test bodies and assertions are unchanged.
Rejected: Implementing full Expat parameter entity parsing | xml-rs does not expose that configuration and the immediate failure is the missing setup API.
Confidence: high
Scope-risk: narrow
Directive: Keep SetParamEntityParsing as a compatibility shim unless the backend grows real Expat-style entity parsing support.

* Keep XML follow-up tests aligned with passing behavior
The pyexpat setup API compatibility fix also makes pulldom's basic parse smoke test pass, so keep RustPython expected-failure markers aligned with current behavior and apply the ruff import-spacing fix.
