[TASK] Separate database requirements checks in Install tool

This change separates database requirement checks regarding the DBMS
platform (e.g. MySQL, PostgreSQL, ...) from drivers as checks for
specific drivers may differ (e.g. pdo_mysql requires other PHP
extensions being loaded than mysqli).

Additionally the encoding for the database is defined in
\TYPO3\CMS\Core\Database\Platform\PlatformInformation
which will be enforced during the install process of the Install tool.
