[USER32][INPUT] Support various keyboard layouts (#4666)

- Fix IntLoadKeyboardLayout function to return the correct HKL value.
- Modify LAYOUT_LIST_NODE structure to add more information.
- Fix LayoutList_GetByHkl function to choose the IME HKLs correctly.
- Ignore DELETED entries correctly.
- Improve UI/UX.
