[GFC] Fix columnsCount() returning 0 when grid has no explicit rows.

<rdar://171102859>
Reviewed by Sammy Gill.
This PR fixes a bug where ImplicitGrid::columnsCount() incorrectly
returns 0 the implicit grid is constructed with zero rows.
We fix this by adding m_initialColumnsCount to the ImplicitGrid
which will track the totalColumnsCount passed in during construction
and save that information regardless of whether we we construct the
first row in m_gridMatrix.
