fix DateTime::modify() and DateTimeImmutable::modify() return types
even though the two methods return types are documented as returning
their respective types, in PHP they are in-fact returning `static`
internally in all versions of PHP currently supported by psalm.

This fixes #9042

e6600fea21 Better type inference and type checking for large union types used in array keys/values
Fixes #8983

This patch adds a basic test showing that, when reaching a union type with 30 elements
or more, Psalm used to fail with an error, because the large union type got simplified
into a more general type as part of performance optimizations done in `TypeCombiner::combine()`.

This means that a type like `array<1|2|3|(etcetera...)|100, mixed>` was internally
simplified to `array<int, mixed>`, after reaching 30 elements or more, which in turn
led to problems and confusing errors when large union types are in play.

Such union types are relatively common in lookup-table-alike value objects.

By removing the hardcoded call-time limit of `30` types to be combined, we hereby
rely on the default `TypeCombiner::combine()` limit of `500` items, which is more
healthy.

This may come with some performance implications, but it is worth trying out, for
now.

Further parameters passed to `TypeCombiner::combine()` that were already matching
parameter default values were also omitted from the call-sites.

45f743f851 Adjusted assertDifferentTypeOfArray test to avoid intersecting incompatible string arrays
Getting one interesting failure caused by the `lowercase-string` refinement done before:

```
  There was 1 error:

  1) Psalm\Tests\AssertAnnotationTest::testValidCode with data set "assertDifferentTypeOfArray" ('<?php\n                    /*...ts[1];')
  Psalm\Exception\CodeException: DocblockTypeContradiction - src/somefile.php:21:21 - Cannot resolve types for $parts - docblock-defined type list{0: lowercase-string, 1?: lowercase-string} does not contain list{string, string}
```

Happens on this bit:

```php
           'assertDifferentTypeOfArray' => [
                'code' => '<?php
                    /**
                     * @psalm-assert list{string, string} $value
                     * @param mixed $value
                     */
                    function isStringTuple($value): void {
                        if (!is_array($value)
                            || !isset($value[0])
                            || !isset($value[1])
                            || !is_string($value[0])
                            || !is_string($value[1])
                        ) {
                            throw new \Exception("bad");
                        }
                    }

                    $s = "";

                    $parts = explode(":", $s, 2);

                    isStringTuple($parts);

                    echo $parts[0];
                    echo $parts[1];',
            ],
```

If I change this to:

```
@psalm-assert list{lowercase-string, lowercase-string} $value
```

Then everything works: I'm wondering if this error has to do with array intersections, and whether suppressing it suffices.

For now, changing the input string, so it is not a `lowercase-string`, is sufficient.

6341d7fef0 Adjusted existing tests to the new signature of explode()
Note how the signature became `array{0: string, 1?: string, 2?: string, array<int, string>}`,
which may be a side-effect of unions between a defined hashmap structure with array
keys, and `list<string>`.

bfded43614 Ensure that explode($d, lowercase-string) produces list<lowercase-string> types
This specific distinction seems to be very important for Psalm, as `explode()` and
`lowercase-string` are used aggressively across the codebase.

Also, this change expands the baseline by a few entries, since some of the code locations
instide Psalm itself have un-checked list destructuring operations, as well as array
access calls on potentially undefined array keys produced by `explode()`, which were
previously just `list<string>`, and are now `array{0: string, 1?: string}`, which is
a bit more precise.

04999b172a Refined explode() types
Fixes #5039

This patch removes the need for a custom function return type
provider for `explode()`, and instead replaces all that with a single
stub for the `explode()` function, which provides types for some of
the most common `$limit` input values.

With this change, the `$delimiter` is enforced to be a `non-empty-string`,
which will lead to downstream consumers having to adjust some code accordingly,
but that shouldn't affect the most common scenario of exploding a string
based with a constant `literal-string` delimiter, which most PHP devs tend to do.

This change didn't come with an accompanying test, since that would be a bit
wasteful, but it was verified locally with following script:

```php
<?php

$possible0  = explode(',', 'hello, world', -100);
$possible1  = explode(',', 'hello, world', -1);
$possible2  = explode(',', 'hello, world', 0);
$possible3  = explode(',', 'hello, world', 1);
$possible4  = explode(',', 'hello, world', 2);
$possible5  = explode(',', 'hello, world', 3);
$possible6  = explode(',', 'hello, world', 4);
try {
    $impossible1 = explode('', '', -1);
} catch (Throwable $impossible1) {}

$traced = [$possible0, $possible1, $possible2, $possible3, $possible4, $possible5, $possible6, $impossible1];

/** @psalm-trace $traced */

var_dump($traced);

return $traced;
```

Running psalm locally, this produces:

```
