Add support for maps as properties

This support enables specifying properties of the type "map" within a
Soong module, but explicitly does not allow them to be used within a bp
file.

This means that rather than specifying each arch/os/target within a
struct to support arch-variant properties/attributes, we can use a map.
This allows us to simplify the implementation of LabelAttribute,
StringListAttribute, and LabelListAttribute as the number of select
statements supported becoming large and hard results in a lot of
duplication.

Blueprint Build System

Blueprint is being archived on 2021 May 3.

On 2021 May 3, we will be archiving the Blueprint project. This means it will not be possible to file new issues or open new pull requests for this GitHub project. As the project is being archived, patches -- including security patches -- will not be applied after May 3. The source tree will remain available, but changes to Blueprint in AOSP will not be merged here and Blueprint's source tree in AOSP will eventually stop being usable outside of Android.

Whereas there are no meta-build systems one can use as a drop-in replacement for Blueprint, there are a number of build systems that can be used:

  • Bazel, Google's multi-language build tool to build and test software of any size, quickly and reliably
  • Soong, for building the Android operating system itself
  • CMake, an open-source, cross-platform family of tools designed to build, test and package software
  • Buck, a fast build system that encourages the creation of small, reusable modules over a variety of platforms and languages
  • The venerable GNU Make
