feat!: Remove deprecated definitions

[aborgna-q]

Remove some deprecated definitions in preparation for tket-rs 0.22.0

BREAKING CHANGE: Removed NormalizeGuppy alias for Normalize pass.
BREAKING CHANGE: Removed legacy QSystemOp re-exports in tket-qsystem.
BREAKING CHANGE: Removed CommandsIterator

Not a breaking python change:
BEGIN_COMMIT_OVERRIDE
chore: Remove deprecated definitions in rust library (#1970)
END_COMMIT_OVERRIDE

[maximilianruesch]

Since this is encoded into the Python package, is removing the read for this metadata not breaking to the Python package in a bad way?

[aborgna-q]

We haven't been writing to this this metadata entry in a while.
We moved to exporting standalone GlobalPhase ops, but left the metadata read path in case someone had a pytket circuit encoded as a Hugr flying around that needed to be re-exported.

Those hugrs are are unlikely to be be stored, so we should be fine removing this now.
