Fix math mode for InsetMathMacro on output

Browse Source 
After 6642152e, user macros were no longer wrapped in \ensuremath. In 2.2 and
before, InsetMathMacro behaved as follow:

* Textmode global symbols are wrapped in \text when in math.

* Other global symbols, and user macros, are wrapped in \ensuremath when in
  text.

* Undefined macros (ERT) are wrapped neither in \text nor in \ensuremath.

This is also consistent with the documentation of MathEnsurer in
mathed/MathStream.h.

This patch defines InsetMathMacro::currentMode() accordingly (respectively
TEXT_MODE, MATH_MODE and UNDECIDED_MODE) and uses it to determine the output.

After this patch, there is a mismatch between screen and pdf output for user
macros in \text. This is not a regression wrt 2.2 and is because linearization
does not satisfy currentMode() currently.

(cherry picked from commit 767f0df18fcd61611de1d1e10e0fd1867479fb59)
