bitbake: bitbake: cooker, command: add a command to return global data

Adding the 'getAllKeysWithFlags' read-only command that will
return a dump of the global data state, together with specified
flags for each key. The flag list is passed in as the first
parameter to the command.

This will be used by UI clients to get the build configuration.
