refactor(library/algebra): move bundled structures to separate module
...
Motivation: performance.
After this commit, the bundled instances do not participate in the
class/instance resolution if we do not import algebra.bundled.

refactor(frontends/lean): add 'attribute' command
...
The new command provides a uniform way to set declaration attributes.
It replaces the commands: class, instance, coercion, multiple_instances,
reducible, irreducible
