Resolves #11002.

Description

What is the purpose of this pull request?

This pull request introduces a new utility @stdlib/ndarray/base/scalar-dtype to resolve a default ndarray data type from a scalar value.

Previously, scalar-to-dtype resolution logic was duplicated across multiple packages such as:

  • ndarray/base/atleastnd
  • ndarray/from-scalar

This PR extracts that logic into a reusable module, improving maintainability, consistency, and making it easier to extend support for additional data types in the future.

Changes include:

  • Adding new package @stdlib/ndarray/base/scalar-dtype
  • Refactoring ndarray/base/atleastnd to use the new utility
  • Removing duplicated scalar dtype resolution logic
