  [lld][WebAssembly] Convert more tests from .ll to .s (#201713)

This continues the work of converting Wasm tests to use assembly instead
of LLVM IR.

For this change I chose all of the `.ll` tests that could be converted
with minimal changed.

Some changes that were needed:
- data-segments.s: Updated segment order and offsets to match .tdata
behavior.
- visibility-hidden.s: Removed __stack_pointer export expectation as
it's no longer automatically exported in the assembly-based test.
- init-fini.s: Updated body encoding and InitFunctions indices to match
llvm-mc output.
- locals-duplicate.test: Added explicit alignment to inputs to match
original test expectations.
- function-imports-first.s, init-fini.s, signature-mismatch-export.s:
Removed __stack_pointer export expectation as it's no longer
automatically exported in assembly-based tests when unused.
- gc-sections.s: Updated expectations to reflect that __stack_pointer is
garbage collected when GC is enabled.
- tag-section.s: Added and exported an explicit global variable
(`my_global`) to ensure a GLOBAL section is created, preserving the test
for checking that the GLOBAL section comes after the TAG section.

To verify the expectation changes, you can use the following command to
diff the .ll (pre-image) and .s (post-image) expectations ignoring
comment character differences:

```shell
git diff --name-status HEAD~1 HEAD | grep '^D' | grep '\.ll$' | while read -r _ ll; do \
  s="${ll%.ll}.s"; \
  if [ -f "$s" ]; then \
    echo "=== Diff for $s ==="; \
    diff -u \
      <(git show HEAD~1:"$ll" | grep -E 'CHECK|RUN' | sed -E 's/^;[[:space:]]*//') \
      <(cat "$s" | grep -E 'CHECK|RUN' | sed -E 's/^#[[:space:]]*//'); \
  fi; \
done
```
