This pull request replaces the PARSE_TIMESTAMP logic with TryCast in datetime operations and optimizes isin_join by utilizing EXISTS instead of IN for multi-column comparisons. A regression was identified in the datetime conversion logic where the op.format parameter is now ignored, which will cause parsing failures for strings that do not follow the default ISO format.

This update addresses issues identified during performance testing against Ibis golden SQL.
datetime_ops: Aligned with Ibis behavior by implementing safe parsing instead of throwing errors.isin_join: Improved performance; benchmark details are available here: [screenshot/vmb8ACvJhDNpccp].
