uriel doyon 3591ea5070 Added some metrics to shrink buffer size when Niagara particles go down significantly. ...

This affects FGlobalDynamicReadBuffer, FGlobalDynamicVertexBuffer and FGlobalDynamicIndexBuffer.

   "r.NumFramesUnusedBeforeReleasingGlobalResourceBuffer"
   Number of frames after which unused global resource allocations will be discarded. Set 0 to ignore. (default=30)

Also added shrinking logic to the FNiagaraDataSet buffers:

   "fx.NiagaraDataBufferMinSize"
   Niagara data buffer minimum allocation size in bytes. (Default=512)

   "fx.NiagaraDataBufferShrinkFactor"
   Niagara data buffer size threshold for shrinking. (Default=3)
   The buffer will be reallocated when the used size becomes 1/F of the allocated size.
