[SYCL] Add error_code support for SYCL 1.2.1 exception classes (#4574)

For ABI compatibility, we are keeping the existing SYCL 1.2.1
exception classes until later. But to improve their conformance
to the SYCL 2020 specification, we want those classes to set
the correct error_code.

[SYCL][CUDA] Windows and MSVC support for CUDA backend (#4345)

Patch adds windows support for CUDA backend. 

Adds general handling of Windows file paths
Windows support is enabled with remangling of variables from PR #4207 as it fixes mismatch between windows 32-bit longs and default 64-bit long and handles wchar_size.
Adds changes to account for MSVC's default to private classes.
Fixes to unittests for windows.

Fix handling of composites in sycl-post-link (#4530)

Enchanced our mini-mangler in SpecConstants pass to avoid generating
`call bitcast` construct when encountering almost the same functions
For example, if you have a call to `%struct.A
__spriv_SpecConstantComposite(i32, i32)` and you try to insert a call to
`%struct.B __spirv_SpecConstantComposite(i32, i32)` you should be having
two calls to two differently mangled functions instead of `call bitcast`
construct, which confuses other toolchain components.
That is achieved by including a mangled return type substring into
the resulting mangling name as `_R{ret-type-mangling}` suffix.

[SYCL] Mark sycl::marray device copyable (#4427)

sycl::marray is device copyable if the element type is device copyable.
Also test was added to verify that the following types are device copyable:
 - sycl::marray<T> when T is device copyable;
 - sycl::vec<T> (all supported element types are device copyable);
 - sycl::id;
 - sycl::range.
