Support for status check pattern (#24633)

This PR is to allow users to specify status checks by patterns. Users
can enter patterns in the "Status Check Pattern" `textarea` to match
status checks and each line specifies a pattern. If "Status Check" is
enabled, patterns cannot be empty and user must enter at least one
pattern.
Users will no longer be able to choose status checks from the table. But
a __*`Matched`*__ mark will be added to the matched checks to help users
enter patterns.

Benefits:
- Even if no status checks have been completed, users can specify
necessary status checks in advance.
- More flexible. Users can specify a series of status checks by one
pattern.
