RFR: 8331021: Deprecate and obsolete the DontYieldALot flag [v2]

[David Holmes]

> The `DontYieldALot` flag is an anachronism from very early Java days - see JBS issue for some details. It should be deprecated for removal in JDK 23.
> 
> BTW the description of the flag:
>> Throw away obvious excess yield calls
> 
> has been incorrect for a long time - it throws away all yield calls.
> 
> As I was changing globals.hpp I also took the opportunity to remove the unused  `DontYieldALotInterval` flag.
> 
> Testing:
>  - tiers 1-3 (sanity)
> 
> Thanks
