We've found that basic profiling could help improving/optimizing when
developing clang-tidy checks.
This PR adds an extra command
```
set enable-profile (true|false) Set whether to enable matcher profiling.
```
which enables profiling queries on each file.
Sample output:
```
$ cat test.cql
set enable-profile true
m binaryOperator(isExpansionInMainFile())
$ cat test.c
int test(int i, int j) {
return i + j;
}
$ clang-query --track-memory -f test.cql test.c --
Match #1:
{{.*}}/test.c:2:10: note: "root" binds here
2 | return i + j;
| ^~~~~
1 match.
