Versionable datetimetype column diff issue

[rmikalkenas]

Bug Report

Q	A
Version	3.3.2

Summary

Platform: MySQL
Version: 8.0

Entity with versionable field:

/**
 * @ORM\Version()
 * @ORM\Column(type="datetime")
 */
private \DateTime $version;

generates the same migration over and over again even after executing it (https://github.com/rmikalkenas/migration-issue/blob/version-issue/migrations/Version20220302083650.php)

An issue comes from changes that adds Comparator with provided database platform as dependency.
When comparing columns this peace of code

dbal/src/Schema/Comparator.php

Line 291 in baf6efe

$changedProperties = $this->diffColumn($column, $toColumn);

returns [] on versionable datetimetype column. But due to set $this->platform later check $this->columnsEqual($column, $toColumn) results to false and marks column as having changes. Because one of Column instances does not have version platform option which is necessary for getting correct mysql datetime column type declaration:

dbal/src/Platforms/AbstractMySQLPlatform.php

Line 249 in baf6efe

public function getDateTimeTypeDeclarationSQL(array $column)

How to reproduce

https://github.com/rmikalkenas/migration-issue/tree/version-issue
version-issue branch

Expected behaviour

No migration should be generated for versionable datetime type column
