Is pre-compile pattern string in regexp_match operation

### Is your feature request related to a problem or challenge?

I noticed below code:
https://github.com/apache/datafusion/blob/6a4a280e3cf70fe5f1a1cfe7c2de13e4c39f89bb/datafusion/physical-expr/src/expressions/binary.rs#L537-L564
This looks like every time record_batch is evaluated, it will execute the compiled pattern string and use the compiled results to match arrow-array

### Describe the solution you'd like

when building binary physical expr , we can pre-compile pattern string if op is regex_match

### Describe alternatives you've considered

### Additional context

Start in datafusion/physical-expr/src/expressions/binary.rs at lines 537-564 and trace how the binary physical expression handles regexp_match during record-batch evaluation. Confirm where the pattern is compiled, then verify that construction-time compilation preserves matching behavior while avoiding repeated compilation for each batch.
