[HLO Componentization] Create hlo/analysis sub-component (Phase II).

This CL takes care of
1. Migrating external projects dependencies from  xla/service --> xla/hlo/analysis

Phase I takes care of
1. Migrating xla/service/<analysis-passes> --> xla/hlo/analysis/<analysis-passes>
2. Setting up build aliases in xla/service ensuring external dependencies are still satisfied.
