Initial (partial) implementation of configured target query. Activated by passing the --post_build_query flag to a build command, with a query expression as the argument. Bazel then executes this query on the configured target graph as constructed by the build command. Since the prepare graph -> query workflow is how SkyQueryEnvironment works, this is mostly just copying that. Main missing features/code cleanups: * Recursive target patterns (/...) are not supported. * There is no way to specify the configuration of the targets in your query. * Configuration output is totally opaque (just the hash, or null if no configuration). * More generally, no output options. * Some features (visibility, label attrs) not supported. * No edge filtering (host deps, implicit deps). * Aspects are totally ignored. * Graceful failure on errors, edge cases, incompatible flags (like the TAP flags that discard edges). * Code hygiene issues (calling test-only method to get to Skyframe graph, some code duplication across ConfiguredTargetQueryEnvironment and SkyQueryEnvironment). Most of the features I plan to leave to rules-side people, since I think they won't be too hard for a general Blaze developer to implement, and designing the right features and user interfaces for these things is better left to the rules side.
