Replace panic with ModuleErrorf
This is a followup cleanup for aosp/2876754 and replaces panic with
ctx.ModuleErrorf. The latter creates a more expressive build error.
Implementation details
- export moduleErrorf interface from build/soong/android. This minimal
interface will be used as a parameter for `DexJarBuildPath`
- Add ModuleErrorf to the function signature of DexJarBuildPath. This
parameter only gets used for Import and SdkLibraryImport structs.
These two can have duplicate deapexer definitions, and ModuleErrorf
will be used to report that error
- Create a minimal implementation of `ModuleErrorf` in tests of java and
apex
Test: m nothing --no-skip-soong-tests
