[pickers] Modify adapter.isValid method to accept TDate | null instead of any

[flaviendelangle]

Fixes #10970

Changelog

Breaking changes

• The adapter.isValid method used to accept any type of value and tried to parse them before checking their validity.
  The method has been simplified and now only accepts an already-parsed date or null.
  Which is the same type as the one accepted by the components value prop.

   const adapterDayjs = new AdapterDayjs();
   const adapterLuxon = new AdapterLuxon();
   const adapterDateFns = new AdapterDateFns();
   const adapterMoment = new AdatperMoment();
  
   // Supported formats
   const isValid = adapterDayjs.isValid(null); // Same for the other adapters
   const isValid = adapterLuxon.isValid(DateTime.now());
   const isValid = adapterMoment.isValid(moment());
   const isValid = adapterDateFns.isValid(new Date());
  
   // Non-supported formats (JS Date)
  - const isValid = adapterDayjs.isValid(new Date('2022-04-17'));
  + const isValid = adapterDayjs.isValid(dayjs('2022-04-17'));
  
  - const isValid = adapterLuxon.isValid(new Date('2022-04-17'));
  + const isValid = adapterLuxon.isValid(DateTime.fromISO('2022-04-17'));
  
  - const isValid = adapterMoment.isValid(new Date('2022-04-17'));
  + const isValid = adapterMoment.isValid(moment('2022-04-17'));
  
   // Non-supported formats (string)
  - const isValid = adapterDayjs.isValid('2022-04-17');
  + const isValid = adapterDayjs.isValid(dayjs('2022-04-17'));
  
  - const isValid = adapterLuxon.isValid('2022-04-17');
  + const isValid = adapterLuxon.isValid(DateTime.fromISO('2022-04-17'));
  
  - const isValid = adapterMoment.isValid('2022-04-17');
  + const isValid = adapterMoment.isValid(moment('2022-04-17'));
  
  - const isValid = adapterDateFns.isValid('2022-04-17');
  + const isValid = adapterDateFns.isValid(new Date('2022-04-17'));
