debug/elf: adjust version API per issue discussion

Browse Source 
This updates the new version API for the discussion on #63952.

This change reveals that in fact none of the tests set the
VERSYM_HIDDEN bit. The code before this CL set the hidden flag
for symbols that appear in DynamicVersionNeed, but that is not
an accurate representation of the ELF. The readelf program
does print undefined symbols that way (with a single '@'),
but that doesn't mean that the hidden flag is set.
Leaving tests with the hidden bit set for later.

For #63952
