CMakeDetermineCompilerABI: Remove -Werror from per-config flags

Extend the fixes from

* commit 079ea66468 (CMakeDetermineCompilerABI: Handle NVCC-style -Werror
  flags, 2020-10-04, v3.19.0-rc1~45^2), and
* commit cec6f98018 (CMakeDetermineCompilerABI: Avoid removing the flag
  after -Werror, 2023-05-29, v3.26.5~4^2)

to apply to the per-config flags propagated by CMP0066's NEW behavior.
