Apply MIBC optimization data when building ASP.NET composite (#47333)

I have verified in the ASP.NET perf lab that the combined
ASP.NET + framework composite image can achieve better startup
perf by about 5% by using the standard MIBC optimization data
so I'm proposing to modify the build script to use it. The
resulting composite image is larger by about 850 KB (Linux x64
without MIBC = 33,853,952 B, with MIBC = 34,702,336 B) so
I believe that thanks to the fact that I recently reduced the
composite image size by more than 30 MB we have sufficient
headroom to make this change.

Thanks

Tomas
