Merge PR #3397: M12: XFA dates are written and read in the field's data picture

Browse Source 
crates/engine/src/tests.rs: union of #3180's new test and #3397's doc comment on the next test.
crates/xfa/src/layout.rs: kept #3782's formatted_value (it calls date_pattern, now built on date_letters) and button_action doc.
crates/xfa/src/parse.rs: parse_field doc comment from #3397 (names the data picture).
crates/xfa/src/script.rs: field() doc from #3582 with #3397's "as scripts read it".
crates/xfa/src/tests.rs: union of fixture imports and of the new tests; one doc comment each for the date-conversion and data-fill tests.
