  [PS5][Driver] Pass `-z rodynamic` to the linker (#115009)

Until now, suppression of `DT_DEBUG` has been hardcoded as a downstream
patch in lld. This can instead be achieved by passing `-z rodynamic`.
Have the driver do this so that the private patch can be removed.

If the scope of lld's `-z rodynamic` is broadened (within reason) to do
more in future, that's likely to be fine as `PT_DYNAMIC` isn't writable
on PlayStation.

PS5 only. On PS4, the equivalent hardcoded configuration will remain in
the proprietary linker.
