Transition away from SPV_INTEL_global_variable_decorations

### Is your feature request related to a problem? Please describe

We are using a deprecated extension `SPV_INTEL_global_variable_decorations`.

### Describe the solution you would like

We should stop using `SPV_INTEL_global_variable_decorations` extension.

For `device_global` we can use [SPV_INTEL_global_variable_host_access](https://github.com/KhronosGroup/SPIRV-Registry/blob/main/extensions/INTEL/SPV_INTEL_global_variable_host_access.asciidoc), the PR https://github.com/intel/llvm/pull/21351 implements this.

Other uses in SYCL are FPGA specific which we no longer support, so we should remove them and finally remove relying on the extension.
