The `CORECLR_EMBEDDED` define that is used in corhost.cpp to detect whether the current host has coreclr and some other native libraries embedded or not doesn't work. The reason is that corhost.cpp is not compiled separately for the cases of embedded and non-embedded coreclr. The proper way is to check the `g_coreclr_embedded` global variable that is defined in the ceemain.cpp, which is compiled separately for those two cases. While we could also make the corhost.cpp build twice, it would be a waste of time.

Port of dotnet#78484, dotnet#78790, dotnet#80104 and dotnet#80294 This change adds detecting and logging of failures during coreclr initialization. For logging, it uses a new host API `coreclr_set_error_writer` to register a callback to report the errors to the host. The hosts have support for optional usage of this API so that they can work with older runtime versions as well. The logging checks and reports failures with: * System.Private.CoreLib.dll * GC initialization * JIT initialization * libSystem.Native.so/dylib on Unix The logging messages should allow customers to self-diagnose the issues causing the failures. This change also adds backport of support for standalone GC back compatibility that is a prerequisite for it.
