Refactor the SymbolName and SymbolAddr types to be pointers

Take the pointer notation out of the typedef such that it preserves the
fact that these are pointers at the use site.

Test Plan:
./validate on all platforms that use the runtime linker.

For unix platforms please ensure `DYNAMIC_GHC_PROGRAMS=NO` is
 added to your validate file.
