Build error in conpty.h due to undefined bool identifier

Windows Terminal version

No response

Windows build number

10.0.19045.7058

Other Software

No response

Steps to reproduce

1. Install the Microsoft.Windows.Console.ConPTY nupkg (including the fixes from Fix MSB4019 error in ConPTY nupkg #20029) into a Visual C++ project.
2. Include <conpty.h> in your source code.
3. Attempt to build the project.

Expected Behavior

The project builds successfully without any errors.

Actual Behavior

The following build errors occur:

Severity	Code	Description	File	Line
Error (active)	E0020	identifier "bool" is undefined	...\inc\conpty.h	45
Error	C2146	syntax error: missing ')' before identifier 'show'	...\inc\conpty.h	45
Error	C2081	'bool': name in formal parameter list illegal	...\inc\conpty.h	45
Error	C2061	syntax error: identifier 'show'	...\inc\conpty.h	45
Error	C2059	syntax error: ';'	...\inc\conpty.h	45
Error	C2059	syntax error: ')'	...\inc\conpty.h	45

Reference: conpty-static.h#L45

In C (prior to C23), bool is not a built-in type.

Could you please update the function prototype for ConptyShowHidePseudoConsole? Or is it expected that we should manually include <stdbool.h> before including <conpty.h>?

I think we should change it to use BOOL instead.
