Friendly overload for MsiFormatRecord() can't accept a null hInstall value.

[mjr4077au]

Actual behavior

Another one where the docs say this should accept a null handle:

Parameters
[in] hInstall

Handle to the installation. This may be omitted, in which case only the record field parameters are processed and properties are not available for substitution.

Expected behavior

That hInstall accepts null, same as mentioned in #2177.

Repro steps

1. NativeMethods.txt content:

MsiFormatRecord

2. NativeMethods.json content (if present): N/A

3. Any of your own code that should be shared? N/A

Context

• CsWin32 version: 0.3.257
• Win32Metadata version (if explicitly set by project): N/A
• Target Framework: net472
• LangVersion (if explicitly set by project): N/A
