Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Implementation Notes:

• Wrapper Strategy: Delegates logic to @stdlib/blas/ext/base/gfill. It extracts the data buffer, stride, and offset from the input ndarray and passes them to the base implementation.
• API Consistency: The function signature is gfill( x, alpha ), consistent with other transformation operations, where x is the input ndarray and alpha is the scalar value to fill.
• Generic Support: Designed to work with any underlying data type (Generic Arrays, Typed Arrays, etc.), handling both numeric and object values.
• Stride Handling: Supports negative strides and non-zero offsets via the base implementation.
