use golang built-in functions rather than mathutil

[lance6716]

Enhancement

like we can use max rather than

tidb/pkg/util/mathutil/math.go

Lines 71 to 80 in 7158ac6

	// Max returns the largest one from its arguments.
	func Max[T constraints.Ordered](x T, xs ...T) T {
	maxv := x
	for _, n := range xs {
	if n > maxv {
	maxv = n
	}
	}
	return maxv
	}

I'll take a look at Monday

@lance6716 I have updated the code using inbuilt function and it is running without errors. Please check it

[lance6716]

@Anudhyan Please read the issue. Use golang built-in functions like https://pkg.go.dev/builtin#max. And delete mathutil. Max

@lance6716 Do I need to do the same for this file only? [tidb/pkg/util/mathutil/math.go]

I have used slices replace custom Max Min functions and removed mathutil.max from line 45 with ^uint64(0). Please guide me if there is any error from my side. I am contributing for the first time!
