Closes #293

Improvements to the print_*_info() functions in both C and Python APIs.

The print_device_info() function now prints the full filter string.

In [2]: d = dpctl.select_gpu_device()

In [3]: d.print_device_info()
    Name            Intel(R) UHD Graphics 630 [0x3e98]
    Driver version  1.0.19438
    Vendor          Intel(R) Corporation
    Profile         FULL_PROFILE
    Filter string   level_zero:gpu:0

The print_platform_info() function now supports verbosity levels that can be 0, 1, 2. The default verbosity level is set to 0.

In [5]: p = dpctl.get_platforms()[0]

In [6]: p.print_platform_info(verbosity=0)
Intel(R) FPGA Emulation Platform for OpenCL(TM) OpenCL 1.2 Intel(R) FPGA SDK for OpenCL(TM), Version 20.3

In [7]: p.print_platform_info(verbosity=1)

In [9]: p.print_platform_info()

The behaviour of the lsplatform function is also modified. Verbosity levels are supported by this function as well and the default level is set to 0. The earlier level of detail is now only printed at verbosity level 2.

Built, ran, got:

In [3]: dpctl.SyclDevice("gpu").print_device_info()
    Name            Intel(R) UHD Graphics [0x9bca]
    Driver version  1.0.19310
    Vendor          Intel(R) Corporation
    Profile         FULL_PROFILE
    Backend         level_zero
    Device type     gpu

Perhaps it would be useful to combine Backend/Device_Type into fully specified filter selector string, kind of like in intel/llvm#3611, using our relative_id routine ?

Where is the relative_id routine? Makes sense to do it right the first time.

Improvements to the print info functions.

  - print_device_info now prints the filter string. Device type
    is no longer separately printed out. Device profile is not
    printed any more.
  - print_platform_info now has various verbosity levels to
    control amount of information that is printed.
