Bug 1574087. Make MathML length, dir, display, displaystyle and mathv…

…ariant case insensitive. r=emilio

See w3c/mathml#22

* mathml/relations/css-styling/attribute-mapping-001.html (length, dir)
* mathml/relations/html5-tree/display-1.html (display)
* mathml/relations/css-styling/displaystyle-1.html (displaystyle)
* mathml/relations/css-styling/displaystyle-2.html (displaystyle)
* mathml/relations/css-styling/mathvariant-case-sensitivity.html (mathvariant)

layout/reftests/bugs/355548-3.xml has been updated now that units are case
insensitive.

Note:
* mathml/relations/css-styling/attribute-mapping-002.html also checks
  case insensitiveness of mathvariant and displaystyle but for now we map
  these attributes to internal -moz-* CSS properties.
* mathcolor and mathbackground values are already case insensitive, this
  is verified by mathml/relations/css-styling/attribute-mapping-001.html
