[SYCL][DOC] Update pipe and pipe properties specifications

[justin-rosner]

This PR updates the pipe and pipe properties specifications to move the latency control properties from the core spec to the pipe properties spec. This implements items 1-2 from this cleanup case.

Item 9, the only remaining issue in this case, is also addressed here by renaming the avalon_mm property to implement_in_csr. Once there is consensus on this name we can update device_globals, kernel arguments, and kernel controls accordingly so that all features that make use of the shared CSR have consistent naming.
