[llvm-pdbutil] Add the ability to dump raw bytes from the file.

Normally we can only make sense of the content of a PDB in terms
of streams and blocks, but in some cases it may be useful to dump
bytes at a specific absolute file offset.  For example, if you
know that some interesting data is at a particular location and
you want to see some surrounding data.
