Feature/han12/combine static (#230)

* replace blt_register_library with blt_import_library

* reorder include of src to the first include. Added ability to build LvArray as cmake object library if a submodule of geosx

* make LvArrayBuildAsObj an option

* rename object libraries flag to LVARRAY_BUILD_OBJ_LIBS
