unwind_user/sframe: Add .sframe validation option
Add a debug feature to validate all .sframe sections when first loading
the file rather than on demand.
Changes since v8: https://lore.kernel.org/20250708021200.223446028@kernel.org
- Add "safe_read_fre()" and "safe_read_fde()" to call their respective
functions with a user_read_access_begin() wrapper around them so that
the validator can simply use dbg_sec() directly instead of a _uaccess()
hacked version.
