move VINTF metadata to /etc/vintf/ .

In particular,
/vendor/manifest.xml => /vendor/etc/vintf/manifest.xml
/system/manifest.xml => /system/etc/vintf/manifest.xml
/vendor/compatibility_matrix.xml =>
    /vendor/etc/vintf/compatibility_matrix.xml

Test: verify that fileis exist in destination
Test: hwservicemanager can read these files
