In the process of using dedicated TCA types,
the new TCA type "file" is introduced and
replaces TCA type "inline" with "foreign_table"
set to "sys_file_reference".

The new type allows to remove a lot of cross
dependencies and special cases for type "inline",
in case the field is used in FAL context. Also
DataHandler and friends benefit from this change,
since dedicated functionality can be used now.

It therefore effectively allows to improve FAL
independently in the future.

Due to the nature of "inline" a lot of code had
to be copied for the new type, while changing the
internal naming was not always easily possible.
This will be done step by step with further patches.

Besides the new TCA type also three new PSR-14 Events
are introduced:

- CustomFileControlsEvent
- ModifyFileReferenceControlsEvent
- ModifyFileReferenceEnabledControlsEvent

While the ModifyFileReferenceControlsEvent and
ModifyFileReferenceEnabledControlsEvent are equal
to their inline counterparts does the CustomFileControlsEvent
replace the "customControls" hook option, which is
therefore only available for type "inline".

Further notable changed:

- Superfluous field "table_local" is removed from "sys_file_reference"
- ExtensionManagementUtility::getFileFieldTCAConfig() is deprecated
- Placeholders are introduced for common image/media/file types
- File extension filtering is now done automatically in FormEngine
  and DataHandler
