disabled test: coff_dwarf standalone test

[andrewrk]

I'm not sure what I did to regress this test in #18160 but I am planning to merge it before fixing it, so here is a tracking issue.

Main test suite...
test
+- test-standalone
   +- standalone.coff_dwarf.test
      +- run main failure
error: the following command exited with code 123 (expected exited with code 0):
C:\actions-runner0\_work\zig\zig\build-release\zig-local-cache\o\4e134fe6248a5ee96d5cdd034662d139\main.exe 
Build Summary: 3545/3758 steps succeeded; 209 skipped; 1 failed; 56645/59644 tests passed; 2999 skipped (disable with --summary none)
test transitive failure
+- test-standalone transitive failure
   +- standalone.coff_dwarf.test transitive failure
      +- run main failure

This test is passing for the x86_64-windows-release and x86_64-windows-debug CI runners.

This issue can be closed when that test is re-enabled for aarch64-windows.
