tsdb: remove chunkRange and oooCapMax from memSeries (#11288) 
* tsdb: remove chunkRange from memSeries

chunkRange is the (oddly-named) configured duration for the head block.

We don't need a copy of this value per series. Pass it down where
required, and remove the copy.

The value in `Head` is only updated in `resetInMemoryState()`, which
also discards all `memSeries`.

* tsdb: remove oooCapMax from memSeries

oooCapMax is the configured maximum capacity for an out-of-order chunk.

Storing it per-series uses extra memory, and has surprising behaviour
if users change the value in config - series created before the change
will keep their old value.

Instead, pass it down where required, and remove the per-series value.
