Implement VectorOp::take

[waynexia]

What problem does the new feature solve?

VectorOp defines a set of basic compute operations.

greptimedb/src/datatypes/src/vectors/operations.rs

Lines 30 to 31 in a9c8584

	/// Vector compute operations.
	pub trait VectorOp {

This ticket requests to add the take method, like this one in arrow. It can construct a new vector out of an existing one, with given indices, which is useful in scenarios like sorting and repeating.

What does the feature do?

Add a new method take to VectorOp
