Fix #5761 by marking all opcache_ functions as impure, as they are affected by runtime/engine (#5762) 
Quoting original issue (fixes #5761):

> Given this snippet ( https://psalm.dev/r/4d51eeab35 ):
>
> ```php
> <?php
>
> function invalidate_cache_for(string $path): void {
>     opcache_invalidate($path);
> }
>
> invalidate_cache_for('foo');
> ```
>
> Psalm reports the `opcache_invalidate()` call as `UnusedFunctionCall`. I'm wondering if `opcache_invalidate()` is perhaps inferred as a pure function? The only reference to it that I could find is in 1a59e81808/dictionaries/CallMap.php, but no purity markers are there.
>
> I'd gladly fix these, if I could get a pointer to where purity is determined.

Improve type resolution of class constants. (#5591) 
Handle array plus operator (fixes #5588).
Handle array spread operator.
Improve string concatenation to resolve to literal instead of unknown string.

I feel like it should be possible to let ConstantTypeResolver take advantage of
the better type analysis in ArrayAnalyzer, ConcatAnalyzer, etc, but it would
require a restructuring that's beyond me for the time being.

Support completions on class references (#5085) 
* Support compleitions on class references

This provides completions on class references (as opposed to initiated objects via the type map), so you can do `MyClass::` and get completitions for static methods and constants etc.

* Only provide completions for references that don't exist

Remove file map cache when re-analyzing files (#5084) 
* Remove file map cache when re-analyzing files

When the project is re-analyzed under the single thread condition (not using a process pool), the filemaps are not cleared before re-analyzing files. This means that file maps only get appended to. If you delete the contents of a file via the LSP, the file map will still be populated with all the old values for example.

In doing this I had to write a few more tests to check my assumptions too, so adding those additional tests.

* Rename test

* Formatting

* Formatting again!
