fix: add .bpl file extension support to PE/DLL cataloger (closes #4664) (#4688)

Borland Package Library (.bpl) files are standard Windows PE/DLL files
used in Delphi and C++Builder ecosystems. This adds the .bpl glob
pattern to the PE file discovery so these files are cataloged alongside
.dll and .exe files.
