1. Add swt.win32.aarch64 fragment and compile natives for Windows on Arm64 …

   This adds the org.eclipse.swt.win32.aarch64 fragment and contains
   changes to the build.bat file, to support compiling the SWT natives for
   the Windows on Arm64 (WoA) platform.
   
   On a WoA box, run the following commands to produce the
   SWT natives (swt*.dll) for WoA:
   
     cd binaries\org.eclipse.swt.win32.win32.aarch64
     mvn clean process-resources -Dnative=win32.win32.aarch64
   
   and the swt*.dll files for WoA will be created in the current directory.
   
   Cross-compiling between the x64 and Arm64 platforms, where either of
   them can be host or target, is also possible, after setting up the
   TARGET_ARCH environment variable with correct target architecture value,
   and with the SWT_JAVA_HOME property pointing to an available JDK of
   the target architecture.
   
   For example, to cross-compile on an x64 host and produce SWT natives for
   Arm64 target, run the following commands:
   
     set TARGET_ARCH=arm64
     cd binaries\org.eclipse.swt.win32.win32.aarch64
     mvn clean process-resources -Dnative=win32.win32.aarch64
   -DSWT_JAVA_HOME=\path\to\arm64_jdk
   
   and the swt*.dll files for WoA will be created in the current directory.
   Note the above SWT_JAVA_HOME property in the command line which points
   to an available Arm64 JDK of the target architecture.
   
   Similarly, to cross-compile on an Arm64 host and produce SWT natives for
   x64 target, run the following commands:
   
     set TARGET_ARCH=x64
     cd binaries\org.eclipse.swt.win32.win32.x86_64
     mvn clean process-resources -Dnative=win32.win32.x86_64
   -DSWT_JAVA_HOME=\path\to\x64_jdk
   
   and the swt*.dll files for x64 will be created in the current directory.
   
   Note that for cross-compiling between x64 and Arm64 to work, install the
   MSVC compiler version 2022, with mandatory build tools for both
   platforms included in the installation.
   
   Once the SWT natives for Arm64 are generated, the SWT binaries module's
   files can be produced with the following build commands in current
   directory:
   
     mvn clean verify -DskipTests=true
   
   and the module's jar/zip files will be produced in the target directory:
   
     org.eclipse.swt.win32.win32.aarch64-<version>.jar
     org.eclipse.swt.win32.win32.aarch64-<version>-sources.jar
     swt-<version>-win32-win32-aarch64.zip
   
   Also add the WebView2Loader.dll version 1.0.1150.38 (matching the
   swt.win32.x86_64 fragment), obtained from the NuGet package
   microsoft.web.webview2
   https://nuget.info/packages/Microsoft.Web.WebView2/1.0.1150.38
   located in the sub-folder build/native/arm64
