scripts/resulttool: do not count newly passing tests as regressions

Browse Source 
resulttool regression module simply compare a base test status to a target test
result status. This approach raises many false positives since all XXX -> PASS
transitions (XXX being any status different from PASS) are flagged as
regression.

- Do not list XXX -> PASS transitions in regression  report, instead count them
  and print a summary of "newly passing tests"
- If an inspected pair has only "newly passing tests", do not print detailed
  list and print it as "Improvement" instead of "Regression"

Updated output example looks like the following:
[...]
Improvement: oeselftest_fedora-37_qemux86-64_20230127010225
             oeselftest_ubuntu-22.04_qemux86-64_20230226120516
             (+1 test(s) passing)
[...]
Match:       oeselftest_almalinux-8.7_qemuarm64_20230127015830
             oeselftest_almalinux-8.7_qemuarm64_20230227015258
[...]
Regression:  oeselftest_almalinux-9.1_qemumips_20230127000217
             oeselftest_opensuseleap-15.4_qemumips_20230226130046
    ptestresult.glibc-user.debug/tst-read-chk-cancel: PASS -> None
    ptestresult.glibc-user.nptl/tst-mutexpi4: PASS -> FAIL
    ptestresult.glibc-user.nptl/tst-mutexpi5a: PASS -> FAIL
    Additionally, 44 previously failing test(s) is/are now passing
