Add a multi-type version of iterateSymbolsWithType

Add a multi-type version of iterateSymbolsWithType

Summary:
When using `folly::symbolizer`, it's very often that we want to use `iterateSymbolsWithType` iterate through symbols of a few types using the same callback. Current approach would require iterating the section multiple times.

This Diff adds `iterateSymbolsWithTypes`, which is basically just `iterateSymbolsWithType` but accepts symbol types.

This Diff also updated implementation of `getDefinitionByAddress` and `getSymbolByName` which currently does two iterations for `STT_OBJECT` and `STT_FUNC`.
