This PR does some (largely superficial) refactoring of the calculate_temperature.c file.

There were 3 commits:

1. I replaced a bunch of occurrences of SUCCESS and FAIL with GR_SUCCESS and GR_FAIL. I also slightly rearranged a little logic within local_calculate_temperature (in preparation for the next commit)
2. I "inlined" the definition of the local_calculate_temperature_table helper function directly inside of local_calculate_temperature (this allowed me to delete local_calculate_temperature_table). For additional context:
   • When I transcribed calc_temp_cloudy_g in PR Update linux-gnu make file for apt-get paths. #34, the definition of local_calculate_temperature_table got a lot shorter. With those changes, local_calculate_temperature_table performed an error-check that primordial_chemistry==0 and simply called `calc_temp_cloudy_g
   • Since local_calculate_temperature only called local_calculate_temperature_table when primordial_chemistry==0, inlining the definition of local_calculate_temperature_table within local_calculate_temperature let us eliminate all associated error-handling logic
   • Consequently, this commit did not increase the number of lines of local_calculate_temperature (or make the logic any harder to follow). At the same time, it allowed us to remove all of the lines of code where we had previously declared/defined local_calculate_temperature_table
3. Finally, I replaced some occurrences of the max macro with C's fmax function. At this point, I was able to remove the include "grackle_macros.h" line
