[Driver] Check that the iOS deployment target is iOS 10 or earlier if
the target is 32-bit.

The following changes are made to the driver since 32-bit apps do not
run on iOS 11 or later:

- If the deployment target is set explicitly, either with a command-line
  option or an environment variable, the driver should report an error
  if the version is greater than iOS 10.

- In the case where the deployment target is not set explicitly and the
  default is inferred from the target triple or SDK version, it should
  use a maximum default of iOS 10.99.99.
