Disable CET enforcement

[EmulationEnjoyer]

Since canary build 1.2.97 when the project was moved to .NET 9 (ref: ff66281), Ryujinx has been failing to launch. The cause is the "Control-flow Enforcement Technology Shadow Stack (.NET 9+)" feature introduced in .NET 9

This specifically affects Windows 10, and more specifically an install of Windows 10 that is not fully up-to-date

This fix allows (Windows 10) systems that are not completely up to date as of the current .NET 9 runtime release to launch Ryujinx. Without this fix the user will receive the following output and an application crash:

CLR: Assert failure(PID 10616 [0x00002978], Thread: 11424 [0x2ca0]): !AreShadowStacksEnabled() || UseSpecialUserModeApc()
File: D:\a_work\1\s\src\coreclr\vm\threads.cpp:7938
Image: Ryujinx.exe

Possible fixes to this issue:

1. User updates their system on top of installing the .NET 9 runtime
2. User disables Control-Flow Guard exploit protection in the Exploit Protection section of the Windows Security applet
3. Merge this pull request to disable CET enforcement by Ryujinx

edit:

Disabling CFG exploit protection does not allow Ryujinx to launch with CET enforcement enabled

For anyone experiencing this issue:

To allow the .NET 9 Ryujinx builds to launch under the condition you are running Windows 10 and the operating system is not fully up-to-date:

1. Open the 'Settings' applet in Windows
2. Search for and open the 'Exploit Protection' panel in the 'Windows Security' applet
3. Select the 'Program settings' column
4. Click 'Add program to customize' and 'Choose exact path'
5. Select the 'Ryujinx.exe' executable file
6. Scroll down to the 'Hardware-enforced Stack Protection' and check the 'Override system settings' option
7. Ensure the toggle is set to 'Off' (even if it was set to 'Off' before checking the 'Override system settings' option, the 'Override system settings' option must still be enabled for it to take affect)

This will allow you to launch and update Ryujinx normally without an immediate crash

(CET was not available in any prior .NET core framework that Ryujinx was compiled against, why is it necessary now?)
