[SYCL] Use global_var_host_access ext for device_global on SPIR-V

[Maetveis]

Change the lowering of the sycl-host-access attribute to use the SPV_INTEL_global_variable_host_access extension instead of the deprecated SPV_INTEL_global_variable_decorations extension.

Newly compiled applications will need to use a recent version of IGC that supports the new extension, but IGC has implemented the support for the new extension more than 6 months ago (in version 2.16.0), so I believe this is ok to do now.

These Windows failures seem related I'm looking into them.

Yep, all of these use device_globals. I cannot reproduce the failures on ARC B580 with Graphics Driver 25.40.1953.2. These failures are probably due to an old driver.
What's the version of GPU driver on the Windows CI machines? Can it be lifted up? @sarnex maybe?

Changes in files owned by me look good.

Not sure about when is the good time to merge the PR, since it will break customers, if they are using older GPU drivers.
