releasetools: Refactor AddImagesToTargetFiles().

Separate three functions out of AddImagesToTargetFiles(), into
AddCareMapTxtForAbOta(), AddRadioImagesForAbOta() and
AddPackRadioImages() respectively. This CL tries to apply minimal
changes for the refactoring purpose.

Also add tests for AddRadioImagesForAbOta() and AddPackRadioImages().
The tests for AddCareMapTxtForAbOta() require better testing support to
mock sparse_img.SparseImage, which will be added in later CLs.

Test: python -m unittest test_add_img_to_target_files
Test: `m dist` with aosp_marlin-userdebug. Check META/care_map.txt in
      the generated target_files.zip.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
