Show where mutated chilled strings were allocated
[Feature #20205]
The warning now suggests running with --debug-frozen-string-literal:
```
test.rb:3: warning: literal string will be frozen in the future (run with --debug-frozen-string-literal for more information)
```
When using --debug-frozen-string-literal, the location where the string
was created is shown:
```
test.rb:3: warning: literal string will be frozen in the future
test.rb:1: info: the string was created here
```
When resurrecting strings and debug mode is not enabled, the overhead is a simple FL_TEST_RAW.
When mutating chilled strings and deprecation warnings are not enabled,
the overhead is a simple warning category enabled check.
