Ban core components from accessing vendor data types · 50563c03

Vendor and system components are only allowed to share files by
passing open FDs over HIDL. Ban all directory access and all file
accesses other than what can be applied to an open FD such as
ioctl/stat/read/write/append.

This commit asserts that core components marked with attribute
coredomain may only access core data types marked with attribute
core_data_file_type.

A temporary exemption is granted to domains that currently rely on
access.

(cherry picked from commit cd97e710)

Bug: 34980020
Test: build Marlin policy
Change-Id: I2f0442f2628fbac1f2f7aa5ddf2a13e16b2546cc
