Subject: Pass in callsite of SurfaceControl constructor explicitly (1/3)

Creating a new Throwable (and filling in the stack trace) can take
up to 150us. Since we do this on the critical path when sending
over SurfaceControl via binder multiple times, this is too much.
Instead, add an option to pass in callsite manually.

Bug: 159056748

Exempt-From-Owner-Approval: Large scale refactor
