[CollapsingToolbarLayout] Set ellipsis to middle of Title in CollapsingToolBar

[venugopalraog]

Is your feature request related to a problem? Please describe.
CollapsingToolbar is setting the Title truncation to End. But as per our requirement we need to set the ellipsis in middle since the last chars in the Title are important we can't ignore or truncate it. Is there any way to achieve it?

Describe the solution you'd like
CollapsingToolbar currently doesn't provide any method to setEllipsize() method so that we can set Ellipsize to middle.

Describe alternatives you've considered
Before setting the Text to Title we have formatted string and added middle ellipsize but problem with this approach is we have to consider all the devices types.

Additional context
Created defect already but it closed with comments current implementation doesn't support and asked to create New Feature request.
