Necessary to avoid problems with implicitly enabled host OS'es, e.g.
linux_glibc getting enabled when we only supply a linux_bionic linker
in runtime-module-host-exports. That will then cause a non-functional
prebuilt to take precedence over source if the prebuilt is preferred.
We don't do this for device since we so far only support a single
device OS (android).
This introduces the notion that SDK member types can be host OS
dependent or not. That way java members with host prebuilts don't get
restricted to a specific host OS.
Test: m nothing
Test: build/soong/scripts/build-aml-prebuilts.sh runtime-module-host-exports
Check that the generated Android.bp correctly disables the bionic
linker prebuilt for linux_glibc.

Test: Add
sdk {
name: "runtime-module-sdk",
native_shared_libs: [
"libc",
"libdl",
"libm",
"ld-android",
],
native_objects: [
"crtbegin_dynamic",
"crtbegin_static",
"crtend_android",
],
}
to bionic/apex/Android.bp. Then:
build/soong/scripts/build-aml-prebuilts.sh runtime-module-sdk
Take the generated runtime-module-sdk-current.zip and unzip into a
master-art tree without bionic/, edit the generated Android.bp to
extend cc_prebuilt_* modules with:
nocrt: true,
stl: "none",
system_shared_libs: [],
apex_available: ["//apex_available:anyapex"],
recovery_available: true,
vendor_available: true,
ramdisk_available: true,
Then "m com.android.art.debug". This passes Soong but fails in the
build step because more members are required.

In preparation for adding cc_library_headers support to
sdk/module_exports.
Two changes were needed to make the prebuilt version work.
1) Had to stop the prebuilt version of the library from creating static
and shared variants for header only.
2) Had to allow the code to export/reexport include dirs to run even
when no src is provided.
