Compute XP thresholds from the client formula instead of the LevelToExp table

Browse Source 
Client ArcCharacter_ExpForLevelUp (0x4715D0): XP to reach level L is
(L-1)^3 * max(1, 1 + (L-40) * 0.0512f) * class * race rune_exp_req_to_level,
rounded half up. getLevel steps levels with it up to LEVELCAP. Both methods
now take the PlayerCharacter so the factors come from its runes; the CSR
promotions 2901+ have no rune and use the base class factor.

Same values: every player race is 10 and every class rune 15, and the formula
equals the removed table for all 76 levels. Levels above the table no longer
use the old approximate fallback.
