Kernel: validate_{string,pointer}_access now return ErrorOr<void>

Now that signals are only processed when returning to userspace,
address validation has to do an early return.

Bootloader: Add support for ext2 blocks up to 4 KiB
...
This should work with blocks bigger than that, but my linux system
only supports up to 4 KiB, so I cannot test this.
This allows getting rid of forced block size in mkfs and let the
program select appropriately sized blocks.

Bochs int 0x10 seems to scrap full ebp and top bits in some
registers. I now save all 32-bit registers on call frame. Also
ebp is across all int 0x10 calls.

Kernel: Implement supplementary groups
...
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...
This allows users to open framebuffer/input files without root.
Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.
