Simplify logic of speed effect frame calculation by using discrete math where possible. Only `SEQ_SPEED_MULTIPLY` mode with animation requires frame map to be built. Frame map building was simplified by removing unused branches. Functional change: Animating strip in negative range will reverse playback. I assume this was limitation of previous system, where each frame map item was limited to be within correct frame range. Now frame map can contain values that point beyond usable range and they are limited by `seq_speed_effect_target_frame_get`. This way it is possible to control playback rate in both directions. Mostly fixes T89120 apart from offset handling. Reviewed By: mano-wii Differential Revision: https://developer.blender.org/D11939
