*: Add support for execute prepared statement to staleread.Processor

[lcwangchao]

What problem does this PR solve?

Issue Number: close #32938

What is changed and how it works?

This is one of the PRs to refactor stale read. The full draft is here: #32325

In the previous implement we parse the execute statement's stale read context in planner phase. This introduces some special codes for execute, for example, we need to reset executorBuilder's context when building Execute instead of when constructing executorBuilder.

This implement removed the above codes and parse the execute's stale read context at the beginning the statement. It is the same logical with select statement, so the processor codes can be reused easily.

This PR also added some unit tests and asserts to check the behavior is the same with the previous implement.
