[SYCL] Align id and range class implementation with SYCL specification

[dsawfer]

"range" and "id" did not correspond to the SYCL 2020 specification: the binary operators were corrected, the necessary operators were added, unnecessary operators were deprecated.

Could you please provide more details on how exactly range and id does not correspond to the SYCL2020 spec?

The DPC++ "range" implementation has a conversion to "id", which is not in the spec, and "id" implementation has a conversion to "range", which is also not in the spec.

As for operators:
The 16 binary operators "+, -, *, /, %, <<, >>, &, |, ^, &&, ||, <, >, <=, >=" are defined as either member functions or hidden friend functions depending on the arguments. However, the spec defines these operators as hidden friend functions for all argument variations.
The 16 binary operators are defined as templates that take any integral type, but the spec defines these operators only for "size_t".
The 10 assignment operators "+=, -=, *=, /=, %=, <<=, >>=, &=, |=, ^=" are defined as member functions, but the spec defines them as hidden friend functions.

In addition, DPC++ is missing the following hidden friend functions which are defined in the spec:
Unary "+" and "-".
Prefix "++" and "--"
Postfix "++" and "--"

Here are pointers to the relevant parts of the spec:
