[SYCL] Include backend-specific header if exists (#4783)

https://www.khronos.org/registry/SYCL/specs/sycl-2020/html/sycl-2020.html#sec:headers-and-namespaces
introduces the backend specific headers "sycl/backend/<backend_name>.hpp"
CTS tests assume that if backend macro is defined (e.g. SYCL_BACKEND_OPENCL)
it is fully functional without extra includes. So the patch adds
include of the backend specific header when the backend is enabled.

The change should fix the recent massive failure of CTS tests with the error:
implicit instantiation of undefined template 'sycl::interop<sycl::backend::opencl, sycl::platform>'

[SYCL][LIBCLC] Change __clc_size_t to unsigned (#4784)

This changes the `__clc_size_t` from a signed 64-bit int to an unsigned 64-bit int. 
The change results in the correct mangled name for `GroupAsyncCopy` built-ins. 

This is a proposed solution to issue #4502

[NFC] Remove accidentally committed file. (#4737)

DPC++ daily 2021-10-16

[sycl-post-link][NFC] Various small refactorings (#4731)

- Replaced `static` functions and variables with usage of anonymous namespace.
- Renamed some functions.
- Applied clang-format to most of the `sycl-post-link.cpp` file.
- Removed some unnecessary includes, added some which were missing (like `<vector>`).
- Added `const` qualifier almost everywhere.
- Updated _some_ comments to use "entry point" instead of "kernel".
  Full replace requires renaming corresponding command line options,
  which should be done in sync with the driver - I would prefer to do so
  in a separate commit.

[SYCL] Use device code cache when building kernel bundles (#4724)

The persistent device code cache, when enabled, is not used when
building the underlying native program in a kernel bundle. These changes
unify cache lookup with a fallback to program creation from
ProgramManager::getBuiltPIProgram with the program creation in
ProgramManager::build, ensuring that the latter also uses cached device
code. Likewise, ProgramManager::build will write the device code to the
persistent cache if it was not there already.
