Revert "Fix redundant condition in Target.cpp"

This reverts commit 9b41609.

The CheckIfWatchpointsSupported function is refactored to maintain the intended behavior as described below:

1. If we can't detect hardware watchpoints, assume they are supported.
2. If we can detect hardware watchpoints and there are more than 0, return true.
3. If we can detect hardware watchpoints but there are 0 of them, set an error message and return false.

fix #87244
