Restructure the bufr sounding job (NOAA-EMC#2853)

The current operational BUFR job begins concurrently with the GFS model
run. This PR updates the script and ush to process all forecast hour
data simultaneously, then combines the temporary outputs to create BUFR
sounding products for each station. The updated job will now start
processing data only after the GFS model completes its 180-hour run,
handling all forecast files from 000hr to 180hr at a time. The new
version job running will need 7 nodes instead of the current operational
4 nodes.

This PR depends on the GFS bufr code update NOAA-EMC/gfs-utils#75

With the updates of bufr codes and scripts, there is no need to add
restart capability to GFS post-process job JGFS_ATMOS_POSTSND.

This PR includes the other changes:

Rename the following table files:

parm/product/bufr_ij13km.txt to parm/product/bufr_ij_gfs_C768.txt
parm/product/bufr_ij9km.txt to parm/product/bufr_ij_gfs_C1152.txt

Add a new table file: parm/product/bufr_ij_gfs_C96.txt for GFSv17 C96
testing.

Added a new capability to the BUFR package. The job priority is to read
bufr_ij_gfs_${CASE}.txt. If the table file is not available, the code
will automatically find the nearest neighbor grid point (i, j).
