As a first step to avoid copy-pasting common code across filesystems which implement fscrypt/fsverity, this commit removes filesystem specific build config option (CONFIG_EXT4_FS_ENCRYPTION, CONFIG_EXT4_FS_VERITY, CONFIG_F2FS_FS_ENCRYPTION and CONFIG_F2FS_FS_VERITY) and replaces it with build options (CONFIG_FS_ENCRYPTION and CONFIG_FS_VERITY) whose values affect all the filesystems making use of fscrypt and fsverity. This is done in order to have a common code base for implementing "post read" processing across filesystems. Changelog: RFC -> V1: 1. Add a new patch to implement S_VERITY/IS_VERITY(). 2. Split code that replaces filesystem specific routines with generic IS_ENCRYPTED() and IS_VERITY() calls into separate patches.
