[TASK] Respect usePasswordPolicyForFrontendUsers in TCA type=password

The feature toggle `security.usePasswordPolicyForFrontendUsers`
introduced in #97390 was added to allow TYPO3 administrators to
still use the deprecated TypoScript validators in ext:felogin
for the password reset process. In order to have a consistent
setup, the feature toggle must also be respected for frontend
users in DataHandler and FormEngine, so it is possible to set
any password, if the feature is turned off.

With this patch, a possible configured password policy for frontend
context (fe_users table) is ignored, if
`security.usePasswordPolicyForFrontendUsers` is set to `false`.

Resolves: #100300
