[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.

[clang-query] Remove support for srcloc output (#92442)

This functionality was added about three years ago, but has been in a
significantly broken state since it was added. It has begun to cause a
maintenance burden for work in Clang (largely due to the complexity of
having two levels of code generation involved), and the original author
is unable to help maintain it. Because it only worked under limited
circumstances and because of the maintenance burden, it is being
removed. If someone wishes to resurrect the functionality, they should
hopefully be able to do so from this one commit.

Fixes #82591

[clang-query] Load queries and matchers from file during REPL cycle (#90603)

The clang-query tool has the ability to execute or pre-load queries from
a file when the tool is launched, but doesn't have the ability to do the
same from the interactive REPL prompt. Because the prompt also doesn't
seem to allow multi-line matchers, this can make prototyping and
iterating on more complicated matchers difficult.

Supporting a dynamic load at REPL time allows the cost of reading the
compilation database and building the AST to be imposed just once, and
allows faster prototyping.

Checks if introspection support is available set output kind parser.
If it isn't present the auto complete will not suggest `srcloc` and an error query will be reported if a user tries to access it.

Make llvm::StringRef to std::string conversions explicit.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
