Improve `qml.ppm_compilation` to able compile from Clifford+RZ/T into PPR/PPM

[sengthai]

Currently, ppm_compilation pass obtains sub-passes such as:

• qml.transforms.to_ppr
• qml.transforms.commute_ppr
• qml.transforms.merge_ppr_ppm
• qml.transforms.ppr_to_ppm

The new passes have been added, such as gridsynth and decompose_arbitrary_ppr.

Here, we should also include these two passes in the PPM compilation pipeline.
So, the passes' order should be:

• qml.transforms.to_ppr
• qml.transforms.decompose_arbitrary_ppr (NEW)
• qml.transforms.gridsynth (targeting PPR basis) (NEW)
• qml.transforms.commute_ppr
• qml.transforms.merge_ppr_ppm
• qml.transforms.ppr_to_ppm
