Kernel: Fix stack OOB detection

are killed if they encouner stack over/under flow.

BAN: String now uses union for its sso storage
...
This allows String to shrink by 8 bytes since Variant's 8 index is
no longer stored in here.
This required me to make Strings max size one bit less, but that
should still be fine. There should never be strings with size of
over half of the computer's address space.

BAN: Rewrite String with small string optimizations
...
String now holds a 15 byte sso buffer. I'm not sure what the size
should actually be but 15 will work for now. Maybe the sso buffer
should be contained in an union with one bit flag in size instead of
variant that uses extra 8 bytes for type index.
This patch buffs sizeof(String) from 24 bytes to 32 bytes on 64 bit.
I assume this is much better version than the old which had to make
allocation even for empty strings :D.

Kernel: Rewrite a lot of ext2 code
...
This commit consists of multiple big changes
1. blocks for inodes are now allocated on demand
- reading from non allocated block will just return zeroes
- writing to non allocated block allocates it
2. code doesn't really use raw pointers anymore
- all casts to uint32_t or structures are now replaced with
spans. either as<T> or as_span<T> which both are bounds
checked
3. code doesn't depend on random macros for accessing indirect blocks
- i added some recursive functions which take care of this :)
