Change some arguments to gdb::string_view instead of name+len

Just some code cleanup. This change has a few benefits:
- Shorter argument list in the functions
- If the caller needs to calculate the string, they no longer
  need to explicitly call strlen
- It is easy to pass std::string to this (done in one place
  currently)

This also updates a couple of places that were passing 0/1 to
a bool parameter.
