Graph decomp rule improvements

[kipawaa]

Context:
The graph-decomposition pass manipulates the decomposition rules in the IR in a number of ways, often duplicating work.

Description of the Change:

• Uses the improved decompose-lowering pass (Add support for choosing decomposition rules in decompose-lowering #2973) to apply exclusively the solver-chosen rules.
• No longer removes user-rules from the IR
• No longer requires re-adding user rules to the IR after decompose-lowering
• No longer requires re-adding the builtin rules for each graph-decomposition pass

Benefits:
A much more efficient and simpler graph-decomposition pass.

Possible Drawbacks:
