cmd/link: collect itablinks as a slice in moduledata

Browse source 
See #14874

This change tells the linker to collect all the itablink symbols and
collect them so that moduledata can have a slice of all compiler
generated itabs.

The logic is shamelessly adapted from what is done with typelink symbols.
