Add a table in dpctl's documentation comparing which SYCL classes and functions are supported

[diptorupd]

DpCtl implements to various degrees the main SYCL runtime classes (ref Section 4.6.4 of SYCL 2020 spec). We need to add a table in our documentation noting what Sycl functions are supported by dpCtl's C and Python APIs and also noting any limitations or unsupported features.

This information is vital to drive adoption of dpCtl as a Python interface to the core SYCL classes.

Something like:

Class device

SYCL Function	dpCtl C-API function	Python API function	Notes
get_info<info::device::driver_version>	DPCTLDevice_GetDriverInfo	get_driver_version

Closing as maintaining such a table manually is extremely cumbersome and fragile. Instead, docstrings for libsyclinterface and Python functions should have a link to the parent sycl function specification. I will open a separate ticket for that purpose (#742).
