Make APPAR_TEMP and DISCOIS variables available when calc_human_stress_indices is FAST

[olyson]

Description of changes

Make APPAR_TEMP and DISCOIS variables available when calc_human_stress_indices is FAST.
These variables do not depend on the more expensive wet bulb calculation (calc_human_stress_indices=ALL).
Accomplish this by moving these variables out from within this if block within HumanIndexMod.F90:

if ( all_human_stress_indices )then

Testing planned or performed, if any:

• ./run_sys_tests -c ctsm5.4.044 --skip-generate -s clm_short --baseline-root /glade/campaign/cgd/tss/ctsm_baselines/ --account P93300041
  Results are bfb except for field list differences as expected:

This was supposed to go on b4b-dev but somehow I've based this on main. Suggestions on how to fix this?
