Enable use of `verbose` option in `time_interp_external2` calls from `data_override`

[J-Lentz]

Description In data_override_mod, rather than calling time_interp_external2 subroutines with a hardcoded verbose=.false. parameter, verbose is now controlled by the debug_data_override namelist variable from data_override_nml. Excess spaces before line-continuation ampersands were removed as well.

Fixes #1398

How Has This Been Tested? Builds on the AMD box with Intel compiler version 2024.1.0.
