Kernel: Rework kernel-side ELF loading
...
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.
This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.

Kernel: Fix bugs in memory regions
...
MemoryRegion::initialize() required size to be page aligned, this is not
necessary.
MemoryBackedRegion::copy_data_to_region() required user-write
permissions for underlying data. This did not matter as memory backed
regions dont support COW memory, but it could lead to bugs later on.

LibInput: KeyEvent to ansi string now handles delete key
...
This allows Terminal emulator to also handle delete key.
The value of `\0x7F` may be wrong as qemu's serial console seems to be
sending `\e[3~`

Terminal: Optimize printing a lot
...
Terminal used to run `yes` at around 400 lines per second
This patch pumps that to over 100'000 lines per second!
There are 2 optimizations done:
1. only invalidate window once after rendering is done
2. if printing more than `rows()` newlines skip prior data
