[TASK] Mitigate deprecated maximum length methods of `AbstractPlatform`

Relying on the default and the maximum column lengths provided by the
Doctrine DBAL is deprecated. The following AbstractPlatform methods
and their implementations in specific platforms have been deprecated:

- AbstractPlatform::getCharMaxLength()
- AbstractPlatform::getVarcharDefaultLength()
- AbstractPlatform::getVarcharMaxLength()
- AbstractPlatform::getBinaryDefaultLength()
- AbstractPlatform::getBinaryMaxLength()

If required by the target platform(s), the column length should be
specified based on the application logic.

Therefore, the `ConnectionMigrator` is getting a new normalization
method specific for this case along with a generic looper which will
be extended in following changes.

As a drive-by the connection class annotations are changed to an
alias from `\TYPO3\CMS\Core\Database\Connection` to `Typo3Connection`.
