Build vendor/odm sepolicies with Android.bp

Browse source 
The following files are built with Android.bp:
- vendor_sepolicy.cil
- odm_sepolicy.cil
- prebuilt_sepolicy

Also, prebuilt_policy.mk is removed as it's now redundant.

Bug: 33691272
Test: build and compare artifacts
Test: build with rvc-dev sepolicy

// vendor/odm sepolicy
//
// If BOARD_SEPOLICY_VERS is set to a value other than PLATFORM_SEPOLICY_VERSION,
// policy files of platform (system, system_ext, product) can't be mixed with
// policy files of vendor (vendor, odm). If it's the case, platform policies and
// vendor policies are separately built. More specifically,
//
// - Platform policy files needed to build vendor policies, such as plat_policy,
// plat_mapping_cil, plat_pub_policy, reqd_policy_mask, are built from the
// prebuilts (copy of platform policy files of version BOARD_SEPOLICY_VERS).
//
// - sepolicy_neverallows only checks platform policies, and a new module
// sepolicy_neverallows_vendor checks vendor policies.
//
// - neverallow checks are turned off while compiling precompiled_sepolicy
// module and sepolicy module.
//
// - Vendor policies are not checked on the compat test (compat.mk).
//
// In such scenario, we can grab platform policy files from the prebuilts/api
// directory. But we need more than that: prebuilts of system_ext, product,
// system/sepolicy/reqd_mask, and system/sepolicy/vendor. The following
// variables are introduced to specify such prebuilts.
//
// - BOARD_REQD_MASK_POLICY (prebuilt of system/sepolicy/reqd_mask)
// - BOARD_PLAT_VENDOR_POLICY (prebuilt of system/sepolicy/vendor)
// - BOARD_SYSTEM_EXT_PUBLIC_PREBUILT_DIRS (prebuilt of system_ext public)
// - BOARD_SYSTEM_EXT_PRIVATE_PREBUILT_DIRS (prebuilt of system_ext private)
// - BOARD_PRODUCT_PUBLIC_PREBUILT_DIRS (prebuilt of product public)
// - BOARD_PRODUCT_PRIVATE_PREBUILT_DIRS (prebuilt of product private)
//
// Vendors are responsible for copying policy files from the old version of the
// source tree as prebuilts, and for setting BOARD_*_POLICY variables so they
// can be used to build vendor policies.
//
// To support both mixed build and normal build, platform policy files are
// indirectly referred as {.(partition)_(scope)_for_vendor}. They will be equal
// to {.(partition)_scope)} if BOARD_SEPOLICY_VERS == PLATFORM_SEPOLICY_VERSION.
// Otherwise, they will be equal to the Makefile variables above.
