Add Exec and Query methods to FakePDO

[M1ke]

Adds other public methods (rather than just prepare() to FakePdo)

The current master branch state of Psalm surfaces the following fails:

ERROR: ArgumentTypeCoercion - src/Parser/SQLLexer.php:24:13 - Argument 4 of preg_split expects int(0)|int(1)|int(2)|int(3)|int(4)|int(5)|int(6)|int(7), parent type positive-int provided (see https://psalm.dev/193)

        return $this->groupQuotedTokens($tokens);

This branch does not resolve these, but also does not add new fails.

I believe this is the correct way to replicate the internal logic

[M1ke]

Not certain if anything new is needed here to replicate internal logic but this does run properly

[M1ke]

So the fail on the build is coming from the query declaration where I've declared:

query($statement, $mode = PDO::ATTR_DEFAULT_FETCH_MODE, $arg3 = null, array $ctorargs = [])

Whereas the tests run on PHP 8 which requires this to be typed as

query(string $statement, ?int $mode = null, mixed ...$fetchModeArgs)

But if we do that it will break on anything <PHP8. I wonder if this requires the tests to be run on the min supported version (PHP 7.1 according to composer.json)?

Thanks!

Please merge/rebase master! I've introduced separate FakePdo classes for PHP 7 & 8, allowing you to use the different APIs without breaking everything.

[M1ke]

So the last Psalm build on actions failed due to a Docker error... to make it build again I pushed some new .gitignore lines - they are relevant but obviously not directly to this PR so I can remove them if needed.

But on the plus side, all checks now pass with the split out PHP7/8 classes!

I'll update the Codeception branch at Codeception/module-db#20 to use a specific class too.
