Resolve or waive linter issues

This PR resolves and/or waives two distinct linter errors identified by Verissimo:

1. Duplicated code in lib/uvm_agents/uvma_obi_memory/src/comps/uvma_obi_memory_drv.sv. Please look at this change carefully. The change is straightforward - two functions have been collapsed into a single function. Having said that the OBI memory Agent is a critical component in our environments, so we want to be cautious about changes to it.
2. Dealing with Verissimo SVTB.32.2.0 (Pass strings by reference). For the most part, these have been waived.
