* Create a new hook to enable data decimation

The `beforeElementUpdate` hook can be used to decimate data. The chart
elements will not be created until after this hook has fired ensuring that
if decimation occurs, only the needed elements will be created.

* Address code review feedback

* Rename hook to beforeElementsUpdate

* Simplify parsing logic

* Add decimation plugin to the core

* Allow a dataset to specify a different data key

* Decimation plugin uses the dataKey feature

* Not totally sure this is right , but since in core.adapters.js override is part of the dateadapter it seems logical it should be there. Should also fix chartjs#8369
* implemented feedback
* Declare the dataAdapter since it will be available at runtime if someone overrides it
* remove declaration. if this is giving problems in the future it might need te be added again
