[SYCL] Specify kernels in kernel_bundle for MultipleDevsCache (#7188)

This commit changes the ProgramRetain test in MultipleDevsCache to be
explicit about which kernels should be included in the corresponding
kernel bundle. This prevents the kernel bundle from inadvertently
building programs that are unrelated to the test.
