selftests: pci_endpoint: Add BAR subrange mapping test case 



Add BAR_SUBRANGE_TEST to the pci_endpoint kselftest suite.

The test uses the PCITEST_BAR_SUBRANGE ioctl and will skip when the
chosen BAR is disabled (-ENODATA), when the endpoint/controller does not
support subrange mapping (-EOPNOTSUPP), or when the BAR is reserved for
the test register space (-EBUSY).
