gnss_sync: fix timestamp to TTI conversion 
* Improve reliability of timestamp to tti conversion

Difftime is not reliable as it might use 32 bit calculation, depending on the system. This leads to wrong frame numbers and subframe indices.
I encountered this Issue when testing the pssch_ue exampel on my system and the conversion from timestamp to frame number and sf idx was wrong.

* Improve GNSS Sync 

Added loop to check for GNSS alignment while syncing.
If the received GNSS signal is weak, synchronization errors might occur while syncing.

Andre Puschmann e563e5918e rf_imp: fail opening RF altogether if specified device fails to open 
we've had a few runs in the CI where opening the specified RF device
failed but the eNB/UE still continued to run, just picking the next available
run. This led to false-positive tests.

The policy should be that whenever the user specified a RF device to
be openend, and this device fails, the whole process should fail and
the application should exit.

The auto-detection mode is still available but only if no device name
is specified at all.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.
