Move Clock Compose Elements into Plugin Libs

In order to provide more flexibility to clock layouts when flexiglass
ships, this change adds compose support to the clock interfaces. This
lets clocks provide composable functions directly back to SystemUI.

Because of how compose is structured, we couldn't include the library
in the same way we included previous libraries (like ConstraintLayout).
Instead, we've needed to include all the libraries statically to fix
issues with kotlin inline compilation, as well as disabling certain
proguard optimizations.

We provide the ability for clocks (like weather) to have more distinct
layouts by providing a dictionary of composable lockscreen elements for
them to render internally. Clocks must be careful that the elements they
are attempting to render are rendered elsewhere at the same time or this
will cause a duplicate key failure within the scene. Currently only the
smartspace elements are migrated to use this mechanism as they are the
only elements that the current weather clock needs to integrate with.
