test: py: load: check null_dev_desc_ok dispatch

Some pytest modules exercising the dispatch added by
  fs: dispatch null_dev_desc_ok filesystems before lookup

test_load_semihosting.py:
  "load semihosting - <addr> <file>" and the optional
  [bytes] [pos] variant. Runs on qemu_arm64 with
  CONFIG_SEMIHOSTING=y; reuses test_hostfs.py's host-staged
  fixture.

test_load_sandbox.py:
  "load sandbox - <addr> <file>" and the optional [bytes] [pos]
  variant. Runs on sandbox (boardspec('sandbox')); the sandbox
  fstype is registered with name="sandbox" and
    null_dev_desc_ok=true,
  so the same fs_lookup_null_dev_info() helper that
  routes semihosting also routes the "sandbox".

A "load ubifs - <addr> <file>" test is intentionally not provided.
UBIFS is built on UBI on MTD, which requires some additional works
that are not available with qemu/sandbox-ing.
