RFR: 8295661: CompileTask::compile_id() should be passed as int

[Damon Fenacci]

Changed return type of `CompileTask::compile_id()` from `int` to `uint`.
Also modified the type everywhere `compile_id` is used (parameters, local variables, string formatting, constant assignments) *as much as possible*.
Added *asserts* to check for valid value range where not possible.
