[FEATURE] autocomplete attributes for forms and fields

[thomasrawiel]

Added autocomplete options for forms and input and textarea fields.

Forms:
Autocomplete token: on/off
<form ... autocomplete="on">

Fields:

• Autocomplete token: on/off/Several options
• Section (optional)
• Type (optional)
• Purpose (optional)
  Section, Type and Purpose are conditionally displayed, depending on the token value

Added a viewhelper that creates the autocomplete token string for fields, which is by section, purpose, type, token
e.g.
<input ... autocomplete="on">
<input ... autocomplete="billing email">
<input ... autocomplete="billing work email">
<input ... autocomplete="section-foo billing home email">
The viewhelper applys rules (as I understand them) from the specs, regarding what is allowed for which field, token type etc. For example select fields allow everything an input allows, but most tokens are not meaningful for select fields and will be ignored by browsers. If a tolen is deemed not meaningful/ allowed for a certain field, the token just won't be rendered (no error message)

Raised required TYPO3 version to 12.4.18 to allow arbitrary arguments in form viewhelper, see thomasrawiel/powermailautocomplete#7

Code adapted from EXT:powermailautocomplete whch has been tested in TYPO3 12 and 13.

Resolves #789
There has been a previous pull request on this topic but I think this one is "more correct" in my opinion

Hi! It's really nice to see this feature integrated into powermail. Do you have an idea when this will be merged into the V12 branch?

@kftw If you can live with this you can install EXT:powermailautocomplete until this feature is added to the powermail core
