TWW beta compatibility

[atti92]

Tweaks for the other PR to allow click casting with the "spell" attribute instead of the "macrotext" attribute.
Changes:

• Fix lua errors in a Dragonflight compatible way:
  • GetSpellInfo -> C_Spell.GetSpellInfo
  • GetSpellTexture -> C_Spell.GetSpellInfo
  • GetTexCoordsForRole
  • GetMouseFocus -> GetMouseFoci
• Fixed ClickCasting:
  • Removed use of "macrotext" when running under TWW beta:
  • Smart resurrection no longer works.
  • Always target feature no longer works.
• Fixed Range checks:
  • IsSpellInRange -> C_Spell.IsSpellInRange
  • merged evoker branch with other classes.
