  [RelLookupTableConverter] Drop unnamed_addr for GVs in entries to avoid generating GOTPCREL relocations (#146068)

The entry in a relative lookup table is a global variable with a
constant offset, such as `@gv`, `GEP @gv, 1`, and so on.

We cannot only consider the case of a trivial global variable. This PR
handles all cases using the existing `IsConstantOffsetFromGlobal`
function.
