wxwidgets.cfg: Added support for more interfaces (danmar#8090)

This pull request expands the function configuration in
`cfg/wxwidgets.cfg` to include additional wxWidgets API methods,
improving coverage and consistency for function bindings. The most
important changes involve adding more methods to existing function
groups and introducing new function entries for various wxWidgets
classes.

### Expanded function bindings

* Added `wxTreeListItem::IsOk` to the function group with
`wxBitmap::HasAlpha` and `wxBitmap::IsOk`, ensuring consistent handling
of `IsOk` methods across more classes.
* Extended the `Layout` function group to include `wxWindow::Layout`,
`wxGrid::Layout`, and `wxPanel::Layout`, in addition to the existing
`wxWindowBase::Layout` and `wxFrame::Layout`. Also, added a new group
for sizer-related `Layout` methods (`wxSizer`, `wxBoxSizer`,
`wxGridSizer`, `wxStaticBoxSizer`).

### New function entries

* Added new function entries for `wxWindow::GetScreenPosition`,
`wxGrid::GetScreenPosition`, `wxDataViewListCtrl::GetItemCount`, and the
static method `wxStandardPaths::Get`, improving API access for these
commonly-used methods.
* Grouped `GetPosition` methods for `wxGridEvent`, `wxMouseEvent`, and
`wxMouseState` into a single function entry, streamlining their
configuration.
