Resolves a part of #14404

Description

What is the purpose of this pull request?

This pull request:

• Adds @stdlib/blas/ext/base/ndarray/dreplicate, an ndarray API wrapper for @stdlib/blas/ext/base/dreplicate, which replicates each element in a one-dimensional double-precision floating-point ndarray a specified number of times.
• Accepts an array-like object containing an input ndarray, an output ndarray, and a scalar replication count (k), following the conventions of existing @stdlib/blas/ext/base/ndarray packages.
• Supports ndarray offsets and strides, including non-unit and negative strides.
• Includes unit tests, benchmarks, TypeScript declarations (index.d.ts and test.ts), REPL documentation, a README, and examples.
