What problem does this PR solve?

Issue Number: #1942

We need to support pushing down the str_to_date function to TiFlash

What is changed and how it works?

Known issue

pingcap/tidb#24928

  1. TiDB has some incompatible parsing results compare with MySQL, the compatible issues are fixed in this PR, but not fixed by TiDB yet (maybe we should also fix them on the TiDB side to make TiDB and TiFlash be consistent)
    • '%b'/'%M' should be case insensitive
    • Parsing an empty string
    • Parsing the day that does not exist in the real world
    • Parsing the "Feb 29th" for leap year and non-leap year
    • Parsing some input for "%r" and "%T"

Related changes
