Bump DotNetPreview version to 6.0.100-preview.1.21109.8

Add linker reflection based workaround, till
the new API is ready to use.
It forces the ILLink to process all the referenced assemblies in our steps,
without it, no assemblies are processed before MarkStep.

Updated apk size reference files. The NET6 linker has more optimizations
enabled, assembly sizes decreased about 0.5% and native shared libraries
are smaller as well - about 0.7%.

Comparison of BuildReleaseArm64 apk test sizes before/after

Testing on CI, looks like illink lost some steps.

The linker doesn't load all assemblies anymore. We depend on processing
of all assemblies before `MarkStep`.

Use reflection as temporary workaround to overcome that, until we have
new API in the linker available to handle our processing as part
of `MarkStep`.
This also gets rid of typo in previous commit, which caused problems
in XF test.

@radekdoulik maybe we should use the same version as macios:

I would like to finish it with 6.0.100-preview.1.21109.8 so that I don't have to remeasure it and fix possible new issues. Will try the preview2 in new PR after that one. Hopefully it will be less bumpy than this one.
