[GSYM] Fix incorrect comparison in gSYM creation (#131197)

There is a bug in `llvm/lib/DebugInfo/GSYM/DwarfTransformer.cpp` where
`StmtSeqVal` was being compared against `UINT32_MAX` rather than the
correct `UINT64_MAX` - thanks @nocchijiang for [pointing this
out](https://github.com/llvm/llvm-project/pull/129196#discussion_r1986203058).

We correct the issue with this patch. For testing - the issue would show
when we have a correct offset of value `UINT32_MAX` - but constructing
such a test is impractical.
