feat: don't use explicit load info from loader

[mkroening]

This PR introduces a new executable submodule to env. This submodule provides information about the loaded kernel image from reserved linker symbols. This lets us remove hermit-entry's LoadInfo containing the loaded image address range and the TLS image information. This is necessary for running Hermit when loaded by something that is not hermit-entry.
