ddl: get latest old table ID before replace view

[tangenta]

What problem does this PR solve?

Issue Number: close #53673

Problem Summary:

When we specify OR REPLACE clause in CREATE VIEW statements, if there is an old view, it will be dropped first. However, this old view ID comes from DDL job arguments:

tidb/pkg/ddl/table.go

Line 311 in 35e09a2

var oldTbInfoID int64

If there are many concurrent CREATE VIEW DDL jobs summiting to the queue, the old view ID maybe outdated. Then we will encounter 'table doesn't exist' error:

tidb/pkg/ddl/table.go

Lines 341 to 344 in 35e09a2

	err = t.DropTableOrView(schemaID, job.SchemaName, oldTbInfoID, tbInfo.Name.L)
	if err != nil {
	job.State = model.JobStateCancelled
	return ver, errors.Trace(err)

What changed and how does it work?

Discard the old view ID from DDL job arguments. Always get the latest old view ID.
