Add missing default value for some Bool cli flags

[wxiaoguang]

In #25959 I forgot to add default values to some Bool flags (which were BoolT in cli/v1, BoolT means default to be true)

This PR adds the default "Value" for them.

Yup, good catch, but I didn't realize that at that time. I vaguely feel that BoolTFlag is not the same as BoolFlag, but can't get out from the wrong way. 😭
