Merge compressedrefs and non-compressedrefs tests builds into one

[llxia]

Related to the work of combining compressedrefs and non-compressedrefs SPECS into the same build, we are planning to merge two tests builds into one (removing _xl). Below are some todos:

• No jvm option will be added for NoOptions. Remove the logic in TKG that adds jvm option -Xcompressedrefs or -Xnocompressedrefs
  https://github.com/AdoptOpenJDK/TKG/blob/6ad0667a194152ba7a5a98d68b39731d6c2922a3/openj9Settings.mk#L23-L29

• Update ottawa.csv to merge compressedrefs and non-compressedrefs into one SPEC.

• And clean up ottawa.csv if possible (not required for this issue)

• Check to see if we can use the same ottawa.csv for internal vmfarm build

As suggested by @pshipton , we will update NoOptions to Mode110 and Mode610 in system tests to cover all cases in mixedref SDK. (Remove the duplicates if it is in special.system)

Also, run enable parallel in system test builds. For sanity and extended, parallel on 2 machines. Switch special.system test builds from subdir to dynamic parallel on 5 machines.

As discussed with @renfeiw , list of items that we need to update:

• update ottawa.csv (see above) - we will start with linux_x86-64_mxdptrs (Add column linux_x86-64_mxdptrs in ottawa.csv adoptium/TKG#122) and Add columns in ottawa.csv for mixed-reference platforms adoptium/TKG#127

• update auto-detection to support mixedref in SPEC detection temporarily (this logic is no longer needed once we have only the mixedref SDK) (Detect mixed reference in envDetector adoptium/TKG#124)

• platform map in Jenkins script: https://github.com/AdoptOpenJDK/openjdk-tests/blob/master/buildenv/jenkins/openjdk_tests#L3
  (Add mixed platforms adoptium/aqa-tests#2087 and Add x86-64_linux_mixed in openjdk_tests adoptium/aqa-tests#2081)

• platform map in TKG (Update buildPlatformMap.properties with mixed references adoptium/TKG#129)

• platformRequirements in playlist.xml. Instead of using vm.cmprssptrs to limit the platform, use Mode.

• VM_SUBDIR may need to be updated https://github.com/AdoptOpenJDK/TKG/blob/a9f45783ccc270f962b7d13ab1bdf4e19f413fba/openj9Settings.mk#L28

• cmdlinetests https://github.com/eclipse/openj9/blob/028355d677a4e63ccd6d7b3e4f66391c64d7d48b/test/functional/cmdLineTests/shareClassTests/ListAllCachesTests/listAllCachesTests.xml#L109
