  [fatlto] Add coroutine passes when using FatLTO with ThinLTO (#134434)

When coroutines are used w/ both -ffat-lto-objects and -flto=thin,
the coroutine passes are not added to the optimization pipelines.
Ensure they are added before ModuleOptimization to generate a
working ELF object.

Fixes #134409.

(cherry picked from commit 268c065eab06b81a0d7256ac62c0865b3781e236)
