[corlib]: Move sre dependency into their own method in `System.RuntimeType`. (#14698)

* [corlib]: Move sre dependency into their own method in `System.RuntimeType`.

Move call to `TypeBuilderInstantiation.MakeGenericType` into a new
`System.RuntimeType.MakeTypeBuilderInstantiation` method to allow the
linker to remove it.

Requires linker PR https://github.com/mono/linker/pull/590.

* Bump linker.

* Bump cecil as well.

* Fix the build.

* Really fix the build.

* Bump API snapshot submodule

* [csproj] Update project files
