[BPI] Replace weights by probabilities in BPI.

Description

[BPI] Replace weights by probabilities in BPI.

This patch removes all weight-related interfaces from BPI and replace
them by probability versions. With this patch, we won't use edge weight
anymore in either IR or MC passes. Edge probabilitiy is a better
representation in terms of CFG update and validation.
