The interpreter for LaTeX style formatting messes up text strings with underscores (to use subscript font). With disable of formatting interpreter the plot title texts from e.g. process_test.m look sane since we don't use formatted text. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>

Pull request overview
This PR fixes the display of plot titles containing underscores in MATLAB/Octave audio test scripts. Previously, underscores were interpreted as LaTeX subscript formatting, making titles with underscores (like filenames or test names) appear incorrectly. The fix disables the LaTeX interpreter for plot titles.
- Updated
title()function calls to disable LaTeX-style text interpretation - Applied fix consistently across three test files (tdfb_test.m, src_test.m, process_test.m)
