[DWARF] - Make collectAddressRanges() return section index in addition to Low/High PC

This change is intended to use for LLD in D33183.
Problem we have in LLD when building .gdb_index is that we need to know section which address range belongs to.

Previously it was solved on LLD side by providing fake section addresses with use of llvm::LoadedObjectInfo
interface. We assigned file offsets as addressed. Then after obtaining ranges lists, for each range we had to find section ID's.
That not only was slow, but also complicated implementation and was the reason of incorrect behavior when
sections share the same offsets, like D33176 shows.

This patch makes DWARF parsers to return section index as well. That solves problem mentioned above.

I had to update the two wasm test binaries because they
used the old style 'name' section which is no longer
supported.
