[LaTeX] Add support for IEEEarray environments (#4123)
This commit... 1. adds support for `\begin{IEEEeqnarray}` math environments. specified by: https://moser-isi.ethz.ch/docs/typeset_equations.pdf inspired by: SublimeText/LaTeXTools#1413 2. fixes `meta.environment.math.block` scope by removing incomplete `.be`. 3. fixes `\end` scope using `keyword.control.flow.end.latex`.
