[native] Move MonoVM runtime to a subdirectory (#9749)

Context: #9572

#9572 is prototyping CoreCLR support, and as part of
that it renamed e.g. `src/native/monodroid` to
`src/native/mono/monodroid` -- "inserting" a "runtime" value
underneath `src/native` -- so that CoreCLR code won't be intermingled
with MonoVM code.

Separate out these file moves into a separate PR, to reduce the size
and review complexity of #9572.
