Remove unused NormalizeString()

 - NormalizeString() has 1 caller:
 - CTextBaseLine::WriteOutput(), which has only 1 caller:
 - CTextPage::WriteOutput(), which has only 1 caller:
 - PDF_GetPageText_Unicode(), which has only 1 caller:
 - PDF_GetPageText(), which has no callers.

Removing this also makes CheckRotate(), NormalizeCompositeChar(),
and CTextPage unused.

Removing those makes CTextBaseline() unused.
Removing that makes txtproc.h unused.

PDF_GetTextStream_Unicode also unused.

... and so on until entire files can be removed.
