6ffd938f98 UnitTests: Skip PageFaultTest if exception handlers are not supported
Page faults should only occur on architectures that support exception
handlers, so skip the test on other architectures to avoid spurious test
failures.

e149ad4f0a treewide: convert GPLv2+ license info to SPDX tags
SPDX standardizes how source code conveys its copyright and licensing
information. See https://spdx.github.io/spdx-spec/1-rationale/ . SPDX
tags are adopted in many large projects, including things like the Linux
kernel.

4ecb3084b7 Apple M1 Support for MacOS
This commit adds support for compiling Dolphin for ARM on MacOS so that it can
run natively on the M1 processors without running through Rosseta2 emulation
providing a 30-50% performance speedup and less hitches from Rosseta2.

It consists of several key changes:

- Adding support for W^X allocation(MAP_JIT) for the ARM JIT
- Adding the machine context and config info to identify the M1 processor
- Additions to the build system and docs to support building universal binaries
- Adding code signing entitlements to access the MAP_JIT functionality
- Updating the MoltenVK libvulkan.dylib to a newer version with M1 support

7925de66b2 RFC: Call the previously-set sigaction in fastmem handler if it's not our address
This "fixes" the android crash handler, so it now correctly shows a
backtrace and other debug info on crash instead of scary kernel messages
on arm64

6eb6fa9bf8 Include unistd.h in memtools.cpp to fix nopch
Fixes falling back to generic on non-windows builds with PCH disabled
leading to runtime crashes and the pagefault test failing. Thanks to

030d467d62 Use PanicAlert instead of PanicAlertT when appropriate
It means less work for the translators... But I'm not too sure
about this, because most of these have already been translated.

2ecd849eab Reorganize faulting stuff. Differentiate between arch- and OS-specific defines.
- Get rid of ArmMemTools.cpp and rename x64MemTools.cpp to MemTools.cpp.
  ArmMemTools was almost identical to the POSIX part of x64MemTools, and
  the two differences, (a) lack of sigaltstack, which I added to the
  latter recently, and (b) use of r10 to determine the fault address
  instead of info->si_addr (meaning it only works for specifically
  formatted JIT code), I don't think are necessary.  (Plus Android, see
  below.)

- Rename Core/PowerPC/JitCommon/JitBackpatch.h to Core/MachineContext.h.
  It doesn't contain anything JIT-specific anymore, and e.g. locking
  will want to use faulting support regardless of whether any JIT is in
  use.

- Get rid of different definitions of SContext for different
  architectures under __linux__, since this is POSIX.  The exception is
  of course Android being shitty; I moved the workaround definition from
  ArmMemTools.cpp to here.

- Get rid of #ifdefs around EMM::InstallExceptionHandler and just
  provide an empty implementation for unsupported systems (i.e.
  _M_GENERIC really).  Added const bool g_exception_handlers_supported
  for future use; currently exception handlers are only used by the JIT,
  whose use implies non-M_GENERIC, but locking will change that.

- Remove an unnecessary typedef.
