[llvm-symbolizer] Add support for -i and -inlines as aliases for -inlining

This change adds two options, -i and -inlines as aliases for the -inlining option to llvm-symbolizer to improve compatibility with the GNU addr2line utility which accepts these options.

It also modifies existing tests that use -inlining to exercise these new aliases as well.

This fixes PR40073.
