gdb: make set/show inferior-tty work with $_gdb_setting_str
Like the previous two commits, this commit fixes set/show inferior-tty
to work with $_gdb_setting_str.
Instead of using a scratch variable which is then pushed into the
current inferior from a set callback, move to the API that allows for
getters and setters, and store the value directly within the current
inferior.
Update an existing test to check the inferior-tty setting.
