[SYCL][Joint Matrix] Relax matrix_combinations error handling (#12866)

This patch relaxes reporting of unsupported HW for matrix_combinations
query.
Before: exception thrown in case customer uses matrix_combinations
query on platform unsupported by ext_oneapi_device_architecture.
With this patch: customer gets empty vector from matrix_combinations
query on platform unsupported by ext_oneapi_device_architecture.
