  tools/tester: Fix crash when hciemu_new fails

When hciemu_new returns NULL, the mgmt object was not being unreferenced
before returning from the pre-setup failure path. This could lead to a
NULL dereference in read_info_callback when it later calls
hciemu_get_address on the NULL hciemu pointer.

Add mgmt_unref and return to the error path across all testers.

  Log Message:
  -----------
  emulator/hciemu: Add hciemu_new_debug/hciemu_new_num_debug

Add new constructors that accept debug callback and user_data parameters,
setting them up immediately after allocation so errors during early
initialization (create_vhci, hciemu_client_new) are captured by the debug
output.

  Log Message:
  -----------
  tools/tester: Retry with debug on hciemu_new failure

When hciemu_new fails, retry using hciemu_new_debug to capture early
initialization errors before reporting the failure. This helps diagnose
issues like vhci or client creation failures in CI.
