[lldb/Interpreter] Fix ambiguous partial command resolution (#101934)

This patch is a follow-up to #97263 that fix ambigous abbreviated
command resolution.

When multiple commands are resolved, instead of failing to pick a
command to
run, this patch changes to resolution logic to check if there is a
single
alias match and if so, it will run the alias instead of the other
matches.

This has as a side-effect that we don't need to make aliases for every
substring of aliases to support abbrivated alias resolution.
