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

#4997 added more precise type inference for count() returning 0 or positive-int on known arrays (#4999)
* #4997 added more precise stub for `count()` returning `0` or `positive-int` on known types

* #4997 updated `count()` to support `\SimpleXmlElement` and `\ResourceBundle` counting, as well as handling hardcoded 2-element-arrays cases

This patch:

 * adds support for `count(\SimpleXmlElement)` (https://www.php.net/manual/en/simplexmlelement.count.php)
 * adds support for `count(\ResourceBundle)` (https://www.php.net/manual/en/resourcebundle.count.php)
 * removes usage of global constants from stub (not supported - see https://www.php.net/manual/en/function.count.php)
 * adds support for identifying fixed-element-count arrays, for example `count(callable&array)`, which is always `2`

* #4997 adapted `FunctionCallReturnTypeFetcher` to infer `TPositiveInt` for `count(TNonEmptyArray)` and `count(TNonEmptyList)`

* The `FunctionCallReturnTypeFetcher` is responsible for defining the precise type of a `\count(T)`
expression when given a `T`, so we baked the whole type resolution for `positive-int`, `0` and
`positive-int|0` directly in there.

While this complicates things, it is also true that it is not possible right now (for the stubs)
to provide the level of detail around `count()` that is required by the type inference system
for such a complex function with so many different semantics.
