Add missing sycl::queue constructors

[al42and]

Hello!

Both SYCL-1.2.1 and SYCL 2020 (provisional) require two additional
constructors for the sycl::queue class, that directly accept device handle instead of device_selector:

explicit queue(const context &syclContext, const device &syclDevice,
    const property_list &propList = {});

explicit queue(const context &syclContext, const device &syclDevice,
    const async_handler &asyncHandler,
    const property_list &propList = {});

They are currently missing in hipSYCL but seem rather trivial to add.

Thank you! :) This is a great addition.

I wonder, would it maybe make sense to map the existing variants with the device selector on these new constructors? E.g. something like this:

explicit queue(const context& ctx, const device_selector& sel, ...)
: queue{ctx, sel.select_device(), ...} {}

@hipSYCL-ci-bot test again
