This commit adds a new transpiler pass RemoveLabeledOps which is used to
remove any op nodes that match a given label. This is paired with a new
label option for BarrierBeforeFinalMeasurements. These are combined in
the preset pass managers to ensure we're not always adding a barrier
before output measurements in the output of the transpiler.

Fixes Qiskit#10321

In the case when a label is set to trigger the removal of the labelled
barrier the merge step would lose the context around which barrier
instruction was transpiler inserted and which was user provided. To
address this issue this commit skips the MergeAdjacentBarrier step so
that the transpiler barrier is kept separate from any user inserted
barriers which need to be preserved.

This commit generalizes the new RemoveLabeledOps pass to be a generic
node filtering pass that given a filter function it will remove any
matching op nodes in the circuit.

This commit inverts the predicate usage to be consistent with Python's
built in filter() function. Now if the predicate returns True the dag node
is retained and if it returns false it is removed. This is also
explicitly documented to make it clear how the pass is to be used.
