Fix GLM_EXT_matrix_common : row to column-major

Browse Source 
The previous patch made the incorrect assumption matrices were row-major
instead of column-major (got the two mixed up in my head).

This fixes this problem.

Also, this extends the test files to cover all matrix sizes (not types,
that would be redundant).
