Summary: We stop tracking at builder boundaries. Let's tract create methods as well so that trace is more informative.

Summary: Before, we didn't track litho framework callees on client code which was wrong. Now, we replace this with the following: If the callee is `build()` itself or doesn't contain a `build()` in its summary, then we want to track it in the domain. The former makes sense since we always want to track `build()` methods. The latter also makes sense since such a method could be a setter for a prop (as in the case of `prop1` in `buildPropLithoOK` which we were missing before due to the imprecise heuristic that prevented picking up callees in litho).

Summary: As a heuristic, litho library calls on non-litho callers are not tracked. This is very imprecise and results in FPs and FNs as exemplified by newly added tests. Instead, we should check to see if the summary contains a `build()` method as will be done in the next diff. This diff adds these tests and refactors the test code.

Summary:
Improve the trace by incorporating the callees and their locations in the call chain (i.e. chain of methods starting from `build()` call)
- extend the domain to contain the callee location
- replace the test results with the new traces
This makes our job much easier to debug FPs in a big codebase.

Summary: `Prop(varArg = myProp) List <?> myPropList` can also be set via `myPropList()` or `myProp()`. Add support for picking up the `varArg` and checking this form of required props.

Summary:
See comment--`Prop(resType = blah) myProp` will generate `.myProp`, `.myPropRes`, and `.myPropAttr`, and any of them can be used to set the prop.
Because our annotation parameter parsing is a bit primitive, handle this by simply checking the `Res` and `Attr` suffixes for every `Prop`.
This shouldn't lead to false negatives because these methods will only exist if the `resType` annotation is specified anyway.

Summary:
This lets us fix the limitation of reporting false positives when a `private` function calls `build()` on a parameter without passing all of the required props.
We will now report such issues in the caller only if it fails to pass the required props.
An unfortunate consequence of this change is that we lose track of where the actual call to `build` occurs--we now report on the declaration of the caller function rather than on the call site of `build`.
I'll work on addressing that in a follow-up.

Summary: At each call to `Component$Builder.build()`, checks that the required props for `Component` have been set via prior calls to the `Builder`. Does not yet handle `Prop(optional = true)`, but will address that in a follow-up.
