Maksim Panchenko ac697b7d3a [BOLT] Replace list of Names with Symbols for BinaryFunction

Summary:
BinaryFunction used to have a list of Names associated with its main
entry point. However, the function is primarily identified by its
corresponding symbol or symbols, and these symbols are available as we
are creating them for a corresponding BinaryData object.

There's also no reason to emit symbols for alternative function names
(aliases), so change the code to only emit needed symbols.

When we emit a cold fragment for a function, only emit one cold symbol
for the fragment instead of one per every main entry symbol/name.

When we match a symbol to an entry point in the function, with this
change we can first go through the list of main entry symbols (now that
they are available).

(cherry picked from FBD19426709)
