Read spell fields through ClassicAPI instead of nampower

Replace GetSpellRecField (nampower) with the C_Spell field readers.

libdebuff reads the dispel type with C_Spell.GetSpellDispelType.

swingtimer detects on-next-swing spells with C_Spell.IsNextMeleeSpell,
and the swing-reset rule with C_Spell.ResetsMeleeSwing. The on-next-swing
check now covers both attribute bits, and the freeze check folds in the
keep-swings attribute, both matching the server rule.

Note: needs the ClassicAPI release that adds these functions. Bump
PFUI_CLASSIC_API_MIN when that version is out.
