Loading Windows CertStore on input plugins

**Is your feature request related to a problem? Please describe.**

https://github.com/fluent/fluent-bit/pull/11009 supports to load certificates from Windows CertStore on output plugins.
This type of functionality should be supported on input plugins.
This work is not implemented for now.

**Describe the solution you'd like**

Loading certificates from Windows CertStore even if input plugins.

Just exporting certificates from Windows CertStore with pem or other types of text formats.
