Implement the 'left' function in issue #98545 (#98942) 
@nik9000  Recheck out the main branch. Refactor the 'left' function to
cut the prefix string in place. But I meet a adversity that left failed
the test case 'testEvaluateInManyThreads'. I find that in multiple
thread situation,  `  EvalOperator.ExpressionEvaluator eval =
evalSupplier.get(); for (int c = 0; c < count; c++) {      
assertThat(toJavaObject(eval.eval(page), 0), testCase.getMatcher()); } `
toJavaObject function return a BytesRef with length=2, content is
[81,89]. However, assertThat function in junit4 receive the BytesRef
parameters that its length is 10. Can you give me some clues? I can't
find which variable is mutual.

Rerun failed test case's command: `gradlew ':x-pack:plugin:esql:test'
--tests
