[BUGFIX] Take tables_modify in PageLayoutView into account

If a non-admin user currently has no access to modify the `tt_content`
table they still get editing options displayed in the PageLayoutView.
Using these options leads to an infinty load of the FormEngine.

Therefore a new function `hasContentModificationAndAccessPermissions`
is introduced which also takes `tables_modify` into account. This function
is now used in various places in PageLayoutView and replaces the current
check which only validates the users access permission.
