Kernel/aarch64: Call handle_crash on unknown exceptions
...
This is useful for debugging, as it will now print out a userspace
backtrace, and optionally also dump the memory regions of the process.

Kernel/aarch64: Remove tpidr_el0 from RegisterState
...
In the next commit, this register will be populated by directly writing
to it, instead of using the RegisterState mechanism.

Kernel/aarch64: Handle SVC exception by calling syscall_handler
...
The SVC (supervisor call) instruction is used in userland to do
syscalls, and this commit adds the handling of syscalls to
Interrupts.cpp.

Kernel/aarch64: Do not dump register state on every page fault
...
This became very spammy, and is not needed anymore since we now
correctly handle page faults.

Kernel/aarch64: Remove static from dump_registers
...
This allows the function to be called from other translation units, in
particular this allows the CrashHandler.cpp file to be shared between
aarch64 and x86_64.

encoding.

Kernel/aarch64: Handle instruction aborts
...
To detect instruction aborts, a helper to Registers.h is added, and used
in Interrupts.cpp. Additionally, the PageFault class gets a setter to
set the PageFaults m_is_instruction_fetch bool, and is also used in
Interrupts.cpp.

Kernel: Replace VERIFY_NOT_REACHED with TODO_AARCH64
...
This makes it easier to differentiate between cases where certain
functionality is not implemented vs. cases where a code location
should really be unreachable.

Kernel: Add support for handling interrupts on aarch64
...
There is currently some code duplication between the aarch64
implementation and the x86 one, but this initial implementation works
for now. :^)

Kernel: Rename idt_init() to initialize_interrupts()

Also move the function out of the x86/Interrupts.h file into the generic
Interrupts.h file and add a stub for aarch64.

Kernel: Add GenericInterruptHandler.cpp to aarch64 build
...
This requires us to add an Interrupts.h file in the Kernel/Arch
directory, which includes the architecture specific files.
The commit also stubs out the functions to be able to compile the
aarch64 Kernel.
