Fix Excel error due to state enum changes (PR #13465)
Summary:
With UIA for Excel disabled, navigating to a cell with a formula and "has formula" was not reported.
This is a regression caused by #13414
In `NVDAHelper/remote/excel.cpp` the properties of a cell were determined and bits were set on the `state` member of a `EXCEL_CELLINFO` struct.
The constants used for this are in `NVDAHelper/remote/excel/Constants.h`, see the `NVSTATE_*` constants, previously these matched the `controlTypes.State` constants directly.
Description of change:
Rather than couple the excel implementation to the controlTypes implementation, these constants have been converted to enums (both in C++ and in Python), renumbered, and an explicit mapping to the corresponding `controlTypes.State` enum has been created.
Fixes #13457
