ConcatAnalyzer improvements and non-falsy-string fixes. (#5544) 
* ConcatAnalyzer improvements.

Deduplicate code.
Improve type inference.
Allow literal type inference when only one side has multiple types (fixes #5483).
Fix invalid type inference with negative int as right operand.

* Fix inference to be lowercase-string when concatenating int.

* Fix TNonEmptyLowercaseString to not be subtype of TNonFalsyString.

'0' is a non-empty-lowercase-string that is falsy.

* Fix other issues with non-falsy-string.

* Nest ands and ors

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.

Fixes vimeo/psalm#5489

properties, this also disabled the checks for arrays, lists,

Allow undefined variable detection in arrow functions (#5343) 
Previously Psalm would assume that any variable it sees in the arrow
function body is defined (and mixed, if it's not available in the outer
scope). This prevented undefined variable detection. Dropping that
assumption allows it to work.

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.

#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.
