rtl: move winiconv.inc into general inc directory and rename it to wincodepages.inc, also rename win2iconv, iconv2win to CodePageToCodePageName, CodePageNameToCodePage.

This change is required since CodePage to CodePage name conversions are required in other parts of RTL. Moreover those codepage identifiers are windows codepage identifiers and thus must be compatible with codepage identifiers used by delphi.
