[analyzer] Remove forbidden characters from a filename for a graph dump on Windows

Summary:
Windows forbidden file path characters are used in a field `file`, while creating a dump `dot` file using an argument -analyzer-dump-egraph. It specifically relates to angle brackets when using `<scratch space>`, `<built-in>`, `<command line>` values in filenames. It causes that script exploded-graph-rewriter.py incorrectly parses the dump.

Fix:
Remove forbidden characters from filename for Windows platform, when creating graph dump file.
