Rename CMake options and C macros to use PUMI_ prefix

I prefixed lots of options with PUMI_ and renamed variables/options with the SCOREC_ prefix which are not created by bob.cmake. In general I set the default value for options like PUMI_ENABLE_SIMMETRIX to ${ENABLE_SIMMETRIX} which allows us to remain somewhat backward compatible and also inherit the selection from parent projects by default.

To find things that needed to be changed, I used the following searches:

git grep '\WENABLE' :^Doxyfile.in :^Doxyfile_internal.in
git grep '\WHAS' :^Doxyfile.in :^Doxyfile_internal.in
git grep '\WHAVE' :^Doxyfile.in :^Doxyfile_internal.in
git grep '\WUSE' :^Doxyfile.in :^Doxyfile_internal.in

I removed the private compile definition -DHAVE_SIMADVMESHING from phasta/CMakeLists.txt and some test exes and replaced it with the PUMI_HAS_SIMADVMESHING macro in apf_sim/apf_simConfig.h. There are some options which are left, specifically Simmetrix things like SIM_PARASOLID, SIM_ACIS, etc that I wasn't sure how we wanted to deal with yet.

An exception that I did not remove is ENABLE_VIZ in test/CMakeLists.txt:

core/test/CMakeLists.txt

Lines 63 to 65 in debc743

	if(ENABLE_VIZ)
	test_exe_func(viz_test viz.cc)
	endif()

I think test/viz.cc can be removed, but Dan forgot to in 0c607cf.

I did not yet change the project name to SCOREC because I wanted to make sure all of these changes work.

Leaving in draft mode for now because there are a few things (Phasta HAVE_CLOCK_/USE_PCU_TIME, LION_COMPRESS, etc) left that I did not get to or am not sure if need to be updated.

Closes #337. Closes #477.
