kvserver: change forTesting suffixes to Testing prefixes for replica.go

Addresses TODO message by @wenyihu6 to do as titled.

Standardize function names to use `Testing` prefix.

Updated test-related functions in `kvserver/replica.go` and related tests to
follow the common `Testing` prefix convention, replacing suffix-based naming.

Fixes: #144119
Release note: None
