This adds support for parsing and dumping the following
symbol types:
S_LPROCREF
S_ENVBLOCK
S_COMPILE2
S_REGISTER
S_COFFGROUP
S_SECTION
S_THUNK32
S_TRAMPOLINE
As of this patch, the test PDB files no longer have any unknown
symbol types.

This makes use of the newly introduced `CVSymbolVisitor` to dump details
of each type of symbol record in the symbol streams. Future patches will
bring this visitor based dumping to the publics stream, as well as
creating a `SymbolDumpDelegate` to print more information about
relocations etc.
