Vadim Zeitlin d013367c24 Backport wxFileDialog::AddShortcut() changes to 3.2
This is a backport of #22635 with the following changes:

- Don't make the new function virtual to avoid changing ABI.
- Use wxABI_VERSION checks around the declarations of the new
  functions (and also constants, for good measure).
- Add new symbol to the linker version script (creating a new
  section for it).
- Document the function as being new in 3.2.1, not 3.3.0.

See #22543.
