Allow external control of whether Glslang will be tested or installed

Browse source 
Expose GLSLANG__TESTS and GLSLANG_ENABLE_INSTALL as options
that can be controlled from an enclosing project, or from the
command line.

They retain the prior default behaviour. In particular, if Glslang
is not the top level project, then they default to OFF.

Fixes: #3507
