VFP Runtime: Implemented AGetFileVersion function with Unit Tests

[Irwin1985]

Hi Team,

This PR implements AGETFILEVERSION() in ArrayFunctions.prg.

• Logic: Uses System.Diagnostics.FileVersionInfo to extract metadata from files (EXE, DLL, etc.).
• Output: Returns the standard VFP 15-element array.
• Mapping: Mapped .NET properties to VFP array positions (Comments, CompanyName, FileVersion, etc.).
• Handling: Handles null properties gracefully (converting to empty strings as per VFP behavior).

Limitations:

• Elements 13 (OLE Self Register) and 15 (Translation Code) are currently returned as empty strings, as FileVersionInfo does not expose the raw Win32 resource data required for these specific fields.

Pull request overview

This PR implements the AGetFileVersion() function in the XSharp VFP runtime, which extracts file version information from executable files and DLLs. The function uses .NET's System.Diagnostics.FileVersionInfo class to populate a 15-element array with metadata such as company name, file version, product name, and other version resource properties.

Changes:

• Implemented AGetFileVersion() function with error handling and null-safe property access
• Added unit tests covering basic functionality and error scenarios
• Removed the TODO placeholder from ToDo-A.prg
