Drop of D49-D85 Phase-2 geometry

[srimanob]

Following the HGCAL proposal in
https://docs.google.com/document/d/1fCIpJJQLw0vGCKyR9LRmFmWVcAQZOlHk5jK-ESQLJnQ/edit?usp=sharing,
they propose to preserve only V16 and V17 of HGCAL (== C17-C19).

So the affected geometries include

• D49 = T15+C9+M4+I10+O4+F2 (HLT TDR baseline)
• D60 = T15+C10+M4+I10+O4+F3 (With HFNose)
• D68 = T21+C11+M6+I11+O5+F4 (For HGCAL study on evolution of detector)
• D70 = T21+C13+M7+I11+O6+F6 (For HGCAL study on evolution of detector)
• D76 = T21+C14+M9+I13+O7+F6
• D77 = T24+C14+M9+I13+O7+F6 (Current default scenario)
• D80 = T25+C14+M9+I13+O7+F6
• D81 = T26+C14+M9+I13+O7+F6
• D82 = T21+C15+M9+I13+O7+F7
• D83 = T24+C16+M9+I13+O7+F6
• D84 = T24+C13+M7+I11+O6+F6 (For HGCAL study on evolution of HGCal replacing D70)
• D85 = T24+C14+M9+I14+O7+F6

This issue is to collect feedback, or need if other version of geometry should be preserved.

The plan is to implement this proposal when the next release series start, i.e. 12_6_X.

Do you still need to keep D49 for HLT?

• will need to add a new scenario with HF nose (compatible with one of the latest HGCal geometries)
• @srimanob @AdrianoDee we may want to take this opportunity to reset the workflow numbers... it's possibly been three years since we last did this in Clean up Phase2 workflows #27449

from the MTD point of view keeping just scenario I15 is ok, this will allow us to drop support in the code for obsolete scenarios (like single disc ring-shaped ETL in D49), simplifying the structure. Some initial cleaning is already proposed for BTL in #38589 (not needing this proposal), in preparation of a new BTL geometry (and MTD scenario) to be added in the coming weeks/months.

This is handled in #38596 (Thanks @bsunanda)
