encoding/xml: reduce depth limit on wasm
Wasm can't handle the recusion for XML nested to depth 10,000.
Cut it off at 5,000 instead. This fixes TestCVE202228131 on trybots
in certain conditions.
Also disable TestCVE202230633 to fix 'go test -v encoding/xml' on gomotes.
Also rename errExeceededMaxUnmarshalDepth [misspelled and unwieldy]
to errUnmarshalDepth.
For #56498.
