Allow setting LCID used by wxAutomationObject.

Default user-locale-dependent LCID may be inappropriate for some situations,
notably Microsoft Excel uses localized formula names for non-English LCIDs.
So add a way to change the LCID to use at wxAutomationObject level while
preserving the old behaviour by default.

Closes #14540.
