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.

933822e400 Do not consider isset checks on static properties as redundant (#5525) 
* Do not consider isset checks on static properties as redundant

Unlike normal properties, static properties do not have a prescribed
initialization sequence, so they can always be uninitialized (or unset).
Thus `isset()` checks on them are never redundant.

Improve type resolution of class constants. (#5591)

the better type analysis in ArrayAnalyzer, ConcatAnalyzer, etc, but it would
require a restructuring that's beyond me for the time being.

Fix array_key_exists() with all int literal keys (#5197) 
When checking code like the following:

```
<?php

function checkNegated(string $key): void {
    $arr = [
        0 => "foo",
        1 => "bar",
    ];

    if (!array_key_exists($key, $arr)) {
        printf("not found\n");
    }
}

function check(string $key): void {
    $arr = [
        0 => "foo",
        1 => "bar",
    ];

    if (array_key_exists($key, $arr)) {
        printf("found\n");
    }
}
```

the `if` in `checkNegated` would cause:

```
ERROR: RedundantCondition - 9:10 - Type string for $key is never =int(0)
```

This happens when the array keys are all int literals, but the "needle"
is a string.

`array_key_exists()` uses a loose equality comparison, but the generated
assertions for this specific case
(`AssertionFinder::getArrayKeyExistsAssertions`) was generating strict
equality clauses. This commit fixes it by changing the generated clause
from `=` to `~`.

Enforce property type invariance (#5131) 
* Implement NonInvariantChildProperty detection

See https://github.com/vimeo/psalm/issues/4184

* Delete test cases with 'parentSetsWiderTypeInConstructor'

As I understand it these are not valid test cases. They
emit NonInvariantPropertyType issues which seems correct - the property
type variation is I think a latent bug in the sample code.

* Reduce shortcode for NonInvariantPropertyType to 1+max used shortcode on master

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!
