firmware: Add VB2_TRY() helper macro

Add variadic macro VB2_TRY() to vboot2 APIs, which supports the
following usage:

- VB2_TRY(func_call())
- VB2_TRY(func_call(), ctx, recovery_reason)

and will return the error code if func_call() failed.

Also utilize the macro whenever possible throughout vboot.
