This allows defining JUCE_LOG_CURRENT_ASSERTION when using Visual
Studio, where escaping semicolons in the command-line is not possible.

This commit adds fixes for generating unique hardware IDs on Windows. The SMBIOS is parsed to generate a unique ID based on hardware factors of the local machine.

Xcode 14 has minimum deployment targets of macos 10.13 and iOS 11.

This is a breaking change - see BREAKING-CHANGES.txt

While the affected callbacks are cancelled before the referenced
state is deleted, we have had user reports that they can still be
accessed by the cancelled callbacks causing crashes. After only
finding warnings that WinRT AsyncCallback cancellation is not a
guaranteed thing, we saw it best to wrap the pointers.

This restores the functionality of JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS.
Using this preprocessor flag may avoid Core Graphics rendering much larger regions than
necessary, but the small regions that are rendered will likely be rendered slower.
Whether using this flag improves or degrades the performance of your rendering overall
will be specific to each application.

Previously enabling JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS was ineffective
from versions of macOS around 10.13, but enabling it didn't have any negative impact on
performance. Now enabling JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS may result
in slower rendering.

With this patch applied, the DemoRunner should build under MinGW, and be
(nearly) feature-complete compared to the MSVC build.

Specifically, when building with MinGW:
- Adds support for accessibility
- Fixes build issues in the juce_video module
- Fixes a link issue in the VST3 wrapper when VST3_CAN_REPLACE_VST2 is
  defined
- Adds support for the new-style native FileChooser
- Tidies up some other low-severity warnings

Known issues:
- Direct2D rendering is still not supported when building with MinGW due
  to ABI compatibilities.
