PR handling port of Diagnostic Server C++ library from CoreCLR into a C

library that can be shared between Mono as well as CoreCLR runtime.

Port follows same guidelines setup for event pipe port dotnet#34600.
Diagnostic server library is currently hosted as part of event pipe
library but hosting its own runtime shim as well as source files
(so could be split into separate library if ever make sense).
Diagnostic Server have dependencies on event pipe library
(and reuse part of event pipe runtime shim from its how shim).

This is the first PR getting the code from diagnostic server codebase
over to C library. Once that is done there will be follow up PR's
starting to enabling more of the CoreCLR tests suites over event pipe
currently depending on diagnostic server and connection between
diagnostic server and event pipe library.

Current state of this PR is port of most diagnostic server code
+ Windows PAL, but currently POSIX PAL is still WIP.
