bitbake: bitbake: siggen: Pass all data caches to hash functions

Passing all the data caches to the task hashing functions allows them to
correctly account for mcdepends in task signatures. This allows tasks to
be correctly re-run when a mcdepends changes.

By default, the legacy behavior is maintained for derived signature
generators by passing a special proxy object that can either be used to
access all multiconfigs or the legacy behavior. If a derived signature
generator is updated, it can set the supports_multiconfig_datacaces
property to instruct bitbake it deals with multiconfigs properly.
