Fix: Handled 3X3 Matrix transpose with the custom input matrix

[Pranava-Pai-N]

Resolves #9197

Changes:

• Converted the provided matrix to its underlying mat3 values before transposing.
• Enabled regression tests for 3x3 matrix and array transpose behavior.
• Kept the existing array-input behavior unchanged.
