Pull request description:

  ## Issue being fixed or feature implemented
  Backports of QT related improvements from bitcoin v22

  ## What was done?
  See commits for list of backports.
  Changes related to improved behavior of columns while resizing for Transactions List and Recent Requests is dropped due to low performance and buggy behaviour. bitcoin-core/gui#205 and bitcoin-core/gui#229 are DNM due to incompatibility with our table view.
  It reverts also #5992 as better fix is found (see css changes).

  ## How Has This Been Tested?
  Run qt app, try to resize main view with overview page.

  ## Breaking Changes
  N/A
