Delete commented code related to trigger configuration in L1Calo online
job options.

- Replace `TriggerFlags.dataTakingConditions` by
  `ConfigFlags.Trigger.availableRecoMetadata`: this flag is used to indicate
  the trigger systems that are enabled during reconstruction. It is set
  based on the L1/HLT keys in COOL or the metadata in the input file.
- Remove obsolete metadataItems setting (the key names are not relevant
  anymore, and we are setting this elsewhere already).
- Deprecate `TriggerFlags.configForStartup`: this flag was used to
  indicate whether trigger keys can be found in COOL. But this is
  essentially the same check as `availableRecoMetadata` performs now.

I did not re-implement the setting of the `DQMonFlags` based on the
available systems. If this is really needed still for the legacy
monitoring it should be done in the relevant DQ job options.

Set `rec.doDPD=False` if no DPD maker script is specified and if not in
pass-through mode.

Move the include of `DataQualityInit_jobOptions` earlier before the
`ConfigFlags` are being locked.

Since we start having multiple CA-based configurations included in
RecExCommon, setup the ConfigFlags via `OldFlags2NewFlags` in
`RecExCommon_topOptions.py` so they can be used downstream.

Also lock the flags (except for DPD making).

The `RecExCommon/RecExCommon_flags.py` file has been obsoleted since many
years and the same-named file from `RecExCond` is being used.

Delete files that have still referenced this old file as they are
clearly obsolete. If in doubt, the path was changed to "RecExCond".

Forward track thinning should not be called if forward tracks are not being built.

Removes in reconstruction the b-tagging obsolete flags to enable SV1 and JetFitter LH used by offline physics validation

`AODFULL` is the default trigger EDM for data reconstruction. No need to
set the deprecated `TriggerFlags`.

Delete the obsolete `BStoESD_Tier0_HLTConfig_jobOptions.py`. There was
essentially no difference anymore to the `T0TriggerGetter`, which it
also called, apart from setting the `Trigger.readBS` flag.

Delete obsolete package. Move the one relevant file to `CaloRec`.

`recAlgs.doTrigger` is obsolete with the Run-3 trigger. Remove the flag
and remaining references to it in trigger configuration.

Also delete the now unused `TransientBS_DetFlags.py`.

Relates to ATR-22725.

The `recAlgs.doTrigger` flag is obsolete with the Run-3 trigger. Remove
all code setting this flag (was already `False` by default).

Relates to ATR-22725.

in some master builds due to a permissions error. Other tests do not have that problem,
and all of those have executable test scripts.

The `isOnline` specific CTP monitoring configuration is definitely
broken and likely not used. Just remove all code and print an error
message. Also delete some other obsolete files.

Delete obsolete testing scripts that are unused and have not been
updated in a very long time:
- `RecExCommon_doall.sh`
- `qtest_run1.sh`
- `qtest_run2.sh`

Fix myTopToptions.py example to work in current master.

- fix configuration when writing both, IDTIDE and IDTRKVALID,
- fix detection whether IDTIDE or IDTRKVALID is written,
- re-add missing truth and SDO content when processing MC,
- re-add NN variables when writing IDTIDE,
- remove IDTIDE and IDTRKVALID track and truth particle decorations
  from the AOD.
- remove btagging decorations from IDTIDE and IDTRKVALID.

Update PhysVal tests to no longer run jet and met validation (AOD no longer contain jet or met data).
Also remvoe trigger validaiton, which is not relevant for offline reco.

Migrated CaloMgrDetDescrCnv to AthMessaging, and made a number of cosmetic and
stylistic changes in CaloMgrDetDescrCnv.cxx.

Dropped two obsolete python scripts:
* CaloDetMgrDetDescrCnv/python/CaloDetMgrDDCnv.py
* CaloDetMgrDetDescrCnv/share/CaloTTDetMgrDetDescrCnv_joboptions.py
and updated their clients.

Fixed broken TestLArDetDescr/share/TestCaloDDE_jobOptions.py

Fixes ATLASRECTS-6508

With this fix, every instance of JetFitter adds its own decoration.
A non-ambiguous naming scheme is adopted, based on jet collection.
Corresponding changes to exclusion / inclusion lists are included.
This fix also makes sure all tracks are decorated.
