[mathml] Implement font-family: math and use it for <math> tags.

This CL implements the generic font family name "math" [1] and use
it as the default family for MathML \<math> tags in the UA stylesheet
[2]. This is done under a new CSSFontFamilyMath experimental feature
implied by the MathMLCore one. This CL only introduces core logic,
with the expectation that it will be refined later:

• font-family: math is not used to pick a math font on Android since
  no font with an OpenType table are pre-installed [3].

• font-family: math just use the harcoded "Latin Modern Math" font
  on other platforms. They should be configurable by the users.

Intent to ship is [4].
