vcl: rename static Impl* functions to lcl_* in map.cxxHEADmaster

Renames several file-local static functions in map.cxx to use the
standard 'lcl_' (local) prefix rather than 'Impl' or no prefix.

In VCL, the 'Impl' prefix is generally reserved for private member
functions of a class. Since these are free static helper functions
restricted to this translation unit, updating them to the 'lcl_'
prefix improves readability and aligns with LibreOffice naming
conventions.

Functions renamed:
- ImplCalcMapResolution -> lcl_calcMapResolution
- ImplLogicToPixel -> lcl_logicToPixel
- ImplPixelToLogic -> lcl_pixelToLogic
- ImplPixelToLogicDouble -> lcl_pixelToLogicDouble
- setMapRes -> lcl_setMapRes
