[gdb/testsuite] Simplify gdb.base/info-types.exp.tcl further

After adding support for --any in match_line, we can simplify
gdb.base/info-types.exp.tcl further: we can add the "All defined types:"
regexp in the output_lines list:
...
        set output_lines \
            [list \
+                "All defined types:" \
+                "--any" \
                 $file_re \
...

Consequently, we can simplify the state machine to track a variable "found"
with values:
-  0 (unmatched)
-  1 (matched)
- -1 (mismatch).

This makes the code generic enough to factor out into a new proc
gdb_test_lines.

Tested on x86_64-linux.
