Add a multi-type version of iterateSectionsWithType

Add a multi-type version of iterateSectionsWithType

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

This Diff add `iterateSectionsWithTypes`, which is basically just `iterateSectionsWithType` but accepts multiple section types.

It is very similar to D6279651. However, in this Diff we did not change implementation of `getDefinitionByAddress` and `getSymbolByName`, since going through `.dynsym` separately would improve the efficiency of single-address or single-symbol lookup. However, for the use cases that we want to iterate through all symbols of an ELF file, this new interface would be useful.
