fix spellcasting_adjustment('caster_level'), [Sorcerer] Makes Sorcerer only boost Magiclysm and Sorcerer spells, add 2 more spells from Magiclysm

[Light-Wave]

Summary

Bugfixes "[Sorcerer] Makes Sorcerer only boost Magiclysm and Sorcerer spells, add latest spells from Magiclysm"

Purpose of change

Make it so that Sorcerer doesn't buff spells from mods like MoM. To do that, spellcasting_adjustment('caster_level') is needed. But it turned out that that was broken, so I fixed that too.
While I was at it, I also added two spells to Sorcerer that were created in #83088.
Fixes #83283.

Describe the solution

Don't throw away preexisting temp_level_adjustment in evaluate_opens_spellbook_data().
Change Sorcerer to use u_spellcasting_adjustment('caster_level', 'mod': 'magiclysm') and u_spellcasting_adjustment('caster_level', 'mod': 'sorcerer')
Added the new spells by running generate_code.py. Found and fixed minor error in generate_code.py.
Changed Bloodrager code to only set the spell level adjustment once per mod.

Testing

Made a Sorcerer with MoM spells before any changes, noticed Sorcerer spell bonuses were applied to all spells.
Made the .json changes, noticed Sorcerer spell bonuses were not applied to any spells at all.
Made C++ changes and compiled, noticed Sorcerer spell bonuses were applied only to the Magiclysm and Sorcerer spells as intended.

Additional context

@Standing-Storm might be happy to know that spellcasting_adjustment('caster_level') is now working correctly.
