[Detail]
Android P add new limitation for property access between
system partition and vendor partition:
1. SET and GET only by system
2. System cannot SET the property which SET/GET by vendor.
3. Allow system and vendor GET the property which SET by vendor.
[Solution]
1. Add new property label mtk_cxp_vendor_prop
2. Modify CXP related SELinux setting

Since Android P, all properties under non_plat/property_contexts
should follow naming rule to add "vendor" prefix, otherwise
VTS will fail.

1. We have too many config properties set by PRODUCT_PROPERTY_OVERRIDES,
and these properties usually are not sensitive and allow all processes to read.
2. Since Android P, properties should follow naming rule to add "vendor",
and then this will cause properties to be labeled as vendor_default_prop.
By default, coredomain is not granted to read vendor_default_prop.
Actually these properties are read widely from system/vendor processes.
3. So we introduce "mtk_default_prop" type that grant read access to
all processes, including system and vendor.
