Fix emitted Option events for repeatable / allow_multiple Starlark flags

If a build_setting is marked as repeatable = True or allow_multiple = True,
then in the command line events we should emit a separate Option message
for each instance of the corresponding flag.

The simplest way to do so is to store the set of repeatable/allow_multiple
flag names, and pass it through the options provider.

Otherwise, we end up with nonsense like `--//my:cflags=[-DX,-DY,-DZ]` in
the emitted events, which cannot be pasted back into the terminal.
