  [clang-query] add basic profiling on matching each ASTs (#114806)

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.
