Feature Request

Is your feature request related to a problem? Please describe:

When adding new optimizer hints #11364 , we have these warnings messages:
"Optimizer aggregation hints are conflicted" for TIDB_HASHAGG and TIDB_STREAMAGG.
"Join hints are conflict, you can only specify one type of join" for Join Hints.

Describe the feature you'd like:

Extract a common error message pattern for conflicted SQL hints, for example:

errMsgPattern := "Conflicted SQL Hints for %s. You can only specify one of these hints: %s"
errConflictedSQLHints := terror.ClassOptimizer.New(codeInternal, errMsgPattern)

errConflictedSQLHints.GenWithStackByArgs(
	"Aggregate",
	strings.Join([]string{"TIDB_HASHAGG()", "TIDB_STREAMAGG()"}, ","),
)
errConflictedSQLHints.GenWithStackByArgs(
	"Join",
	strings.Join([]string{"TIDB_HJ()", "TIDB_SMJ()", "TIDB_INLJ()"}, ","),
)
