Create separate runtime for per-tuple measurements

[ausbin]

Third time's the charm!

(For context for future readers: it is useful to have statistics on a per-tuple level versus a per-qubit level)

Testing

ctest and manual testing with qir-xacc:

$ build/bin/qir-xacc -i examples/qwerty/bv1101.ll --group-tuples --no-print-accelbuf -a qpp
tuple ret length 4 distinct results 1
tuple ret result 1101 count 1024
tuple discarded length 0 distinct results 0
$ build/bin/qir-xacc -i examples/qwerty/bv1101.ll --group-tuples -a qpp
{
    "AcceleratorBuffer": {
        "name": "qreg_0x5633ea6eb6e0",
        "size": 4,
        "Information": {},
        "Measurements": {
            "1101": 1024
        }
    }
}
tuple ret length 4 distinct results 1
tuple ret result 1101 count 1024
tuple discarded length 0 distinct results 0
$ build/bin/qir-xacc -i examples/qwerty/ghz5.ll --group-tuples --no-print-accelbuf -a qpp
tuple ret length 5 distinct results 2
tuple ret result 00000 count 493
tuple ret result 11111 count 531
tuple discarded length 0 distinct results 0
$ build/bin/qir-xacc -i examples/qwerty/ghz5.ll --no-print-accelbuf -a qpp
tuple ret length 5
qubit 0 experiment <null>: {0: 518, 1: 506}
qubit 1 experiment <null>: {0: 518, 1: 506}
qubit 2 experiment <null>: {0: 518, 1: 506}
qubit 3 experiment <null>: {0: 518, 1: 506}
qubit 4 experiment <null>: {0: 518, 1: 506}
tuple discarded length 0

I have not tested Qwerty end-to-end yet because there are 2-3 more PRs needed to upstream all my changes, some of which may take a while. But the (tuple-grouped) output is the same as it expects

[ausbin]

The build appears to be broken in main, since code in main refers to things this PR defines:

qiree/test/qirxacc/XaccQuantum.test.cc

Line 14 in e03f8a9

#include "qirxacc/XaccDefaultRuntime.hh"

Merging this PR will fix this.

@ausbin sorry for the long time it took to get this... we've finally now got the ability to build xacc for testing. Once #8 is merged you can revert def9076 and rebase this on main. Thanks!

Looks reasonable. Sorry for the delay in reviewing!
