Encoder memory reduction: avoid the allocation of tip_frame buffer during LAP stage

The allocation of buffers corresponding to 'tip_frame' and 'tmp_tip_frame' occurs during both the LAP and ENCODE stages. However, these buffers remain unused during the LAP stage. Therefore, This patch avoids their allocation during the LAP stage.

Heap Memory Savings (%):

2.8% for 4k, 1.8% for 1080p, 2.1% for 720p, 1 - 2% for 360p, and 0.6 - 1.6% for 270p.

This change is verified to be bit-exact with no impact on encode-time.
