Add baseline fuzz configuration

[stephenegriffin]

This pull request includes significant changes to the mapistub.vcxproj file to add new configurations for fuzz testing across different platforms. The changes involve adding new project configurations and corresponding property groups for each platform.

New project configurations:

• Added new project configurations for Fuzz testing across ARM64, ARM64EC, Win32, and x64 platforms.

New property groups for each platform:

• Added property groups for Fuzz|Win32 with settings for static library configuration, Unicode character set, and various compiler and linker options.
• Added property groups for Fuzz|x64 with similar settings as Fuzz|Win32.
• Added property groups for Fuzz|ARM64EC and Fuzz|ARM64 with settings for static library configuration, Unicode character set, and additional compiler and linker options. [1] [2]

Import groups and item definition groups:

• Added import groups for each new Fuzz configuration to include user-specific property sheets. [1] [2] [3] [4]
• Added item definition groups for each new Fuzz configuration with detailed compiler and linker options to optimize for fuzz testing. [1] [2] [3] [4]
