RFR: 8314220: Configurable InlineCacheBuffer size [v3]

[Ekaterina Vergizova]

> InlineCacheBuffer size is currently hardcoded to 10K.
> This can lead to multiple ICBufferFull safepoints for InlineCacheBuffer cleanup and possible performance degradation.
> 
> Added experimental command line option InlineCacheBufferSize with the same default value, allowing it to be configured for performance experiments with ICBufferFull safepoints frequency.
