Test snippets with Delphi 11 & 12 and update results in database

[delphidabbler]

Although the database now supports Delphi 11 (see issue #2) and Delphi 12 (see issue #26), only the very newest snippets have compile results set for Delphi 11 and Delphi 12 (see issue #20 and issue #25).

All other snippets need to be updated to include Delphi 11 & 12 results.

This is a big job and could be done one category file at a time:

• [ ] arrays.ini
• [ ] consts.ini
• [ ] date.ini
• [ ] drive.ini
• [ ] encoding.ini
• [ ] file.ini
• [ ] graphics.ini
• [ ] hex.ini
• [ ] io.ini
• [ ] maths.ini
• [ ] multimedia.ini
• [ ] registry.ini
• [ ] shell.ini
• [ ] string.ini
• [ ] structs.ini
• [ ] sys.ini
• [ ] types.ini
• [ ] utils.ini
• [ ] wb.ini
• [ ] web.ini
• [ ] windows.ini
• [ ] winsys.ini

This issue may be held until:

1. CodeSnip's batch test feature is implemented (https://github.com/delphidabbler/codesnip/issues/16)
2. A tool has been written to help with importing (https://github.com/delphidabbler/code-snippets/issues/22)
