Use basis argument for Decomposition/BasisConversion passes

[lmondada]

This was an old outstanding task following #3644. There is now a simpler 'declarative' way of defining which basis gates to decompose to, without having to explicitly list all patterns.

• Replace explicit enable-patterns lists with the basis argument in Decomposition pass usage across 5 target YAML files (braket, scaleway, tii, infleqtion, quantum_machines) and the OpenQASM pipeline
• Remove redundant disable-patterns=R1ToU3 from all 8 BasisConversion pipeline definitions, as the pattern selection algorithm (introduced in Add Decomposition Pattern Selection logic #3644) handles this automatically
• Remove disable-patterns=R1ToU3 from BasisConversion test RUN lines

The pattern selection algorithm selects decomposition patterns via backward traversal of a decomposition pattern graph, choosing the shortest path to the target basis. This makes manually curating pattern lists unnecessary.
