vbo: increase VBO_SAVE_BUFFER_SIZE from 8k to 256k dwords

Increases the performance of legacy geometry-heavy apps
still using display lists.

Performance increase for a targeted testcase is on the
order of 8x, and applications like ParaView 4.x (5.x uses
no longer used display lists) improve by about 10%-20%.
