Bug 1882817 - Convert reftest for stretchy equal sign to an internal …

…WPT. r=emilio This is a mismatch reftest introduced in bug 854339 to verify it is possible to horizontally stretch the equal sign using unicode-based glyph assembly such as the ones described in [1]. This is non-normative, so keep it as an internal test for now.
