[FEATURE] Allow CEs to be saved directly in NewContentElement wizard

When creating content elements via the NewContentElement wizard,
a new option "saveAndClose" can be defined via PageTSconfig
to skip the "FormEngine" part and save a record directly.

This is especially handy for Content Types like "divider" or
for extensions handling with grids.

This saves clicks for the editor, and matched with the
tt_content_defVals it would be possible to create "quick create"
content elements directly via the New Content Element wizard
with pre-defined values.

The feature is enabled by default for the CType "divider".
