* Port set of changes from single-exe branch * Enable precompilation of marshalling IL stubs in crossgen2 #26767 * P/invoke pregeneration fixes #27389 * Fixes to array marshalling pregeneration #27425 * Fix IsBlittableType #27436 * Fix stack overflow issue and m_alignpad==0 assert I've found that the changes from single-exe had issues - it was causing stack overflow during compilation of a couple of runtime assemblies. After I've fixed that, there was about 15 tests failing at runtime failing with assert failure: m_alignpad == 0. This is a well known indication of a problem where JIT and crossgen get different field offsets, resulting in writing beyond the end of an object. The problem was caused by incorrect usage of sequential layout for class without LayoutSequential attribute. I've added a commit with fix for those to this PR.

Today I learned about
LCIDConversionAttribute.This makes us pass more of the interop tests, but there's still stuff to fix. See individual commits.
