markdownToHtml() unconditionally replaced & with & and > with >, assuming input always comes from innerHTML (where the browser re-serializes entities). For data-include fetched text, this caused double-escaping: authors had to write & to get & in output. Add a fromHTML option (default true for backward compat) that skips the replacement when the text comes from a raw fetch. Partially addresses #4096

This needs a test.

Added a test in tests/spec/core/data-include-spec.js (commit test(core/data-include): add test for entity unescape fix in raw markdown).
The test covers the regression case: > in raw data-include markdown must not be converted to > (which would incorrectly produce a blockquote). It also verifies that a literal > in raw content still correctly becomes a <blockquote> element.

Skip the &/> entity replacement in markdownToHtml when the
