[runtime] Rework named mapping to use an unlinked file to provide correct mapping semantics.

Instead of using mono_valloc we create a temp file and unlink it. With this we can have the right
mmap semantics regarding CoW and access rights.

This does simplify the code too by completely removing the mapping kind.
