Subject: [PATCH 1/2] fix: guard breakpoint() with x86 check for ARM64 Windows
 support

The breakpoint() function uses x86-specific intrinsics (__stosb, __movsb)
and x86 debug registers (Dr0, Dr7 from CONTEXT) that don't exist on ARM64
Windows. This causes compilation to fail when targeting aarch64-pc-windows-msvc.

Added the same #if (!x86) return false; #endif guard that msr() already uses.

Subject: [PATCH 2/2] fix: use #else instead of #endif for x86 guards in msr(),
 kvm_interception(), and breakpoint()

The previous pattern (#if (!x86) return false; #endif) inserts an early
return but the compiler still compiles the code below. MSVC on ARM64
fails because x86-specific intrinsics (__readmsr, __stosb, __movsb) and
x86 debug registers (Dr0, Dr7) don't exist on that platform.

Changed all three functions to use #if (!x86) return false; #else ... #endif
so the x86-specific code is completely excluded from compilation on non-x86
targets.
