CheckLanguage: Avoid CMP0126 warning
The macro's implementation converts a normal variable into a cache
variable intentionally, so both are set. Explicitly set CMP0126 to NEW
to avoid a warning in trace mode. This won't affect the module behavior
because the code path does not activate if a normal variable is already
defined anyway.
Fixes: #22548
