  [clang][DebugInfo] Disable VTable debug info (#130255) on COFF platforms

On COFF platform, d1b0cbff806b50d399826e79b9a53e4726c21302 generates
a debug info linked with VTable even if that is dllimport-ed. That
causes an access violation while performing runtime pseudo-relocation
if the debug section is stripped.
For the release branch, we simply disable VTable debug info on COFF
platform to avoid this problem.

Fixes #149639
