[REFACTOR] driver.h -> driver_api.h (#4760)

"driver" normally refers to the "main" function.
Rationale: the header exposes set of APIs to drive compilation
and should be named as driver api to best reflect its usage.

  * This module provides end-to-end utils to drive the compilation process.
  * We adopt the term "compiler driver" in common compiler infrastructures.
  * Note that a compiler driver is different from "runtime drivers".
  * Most of runtime related code are defined in the runtime folder instead.
