[feat] support Azure Trusted Signing for signing tauri app

[anatawa12]

Describe the problem

Many certificate authority sells certificates with high price.
Recently Microsoft released Azure Trusted Signing for code signing and it's relatively cheap.

However, since signing tauri apps are completely integrated inside tauri cli and tauri cli doesn't have option to customize /dlib, /dmdf parameters for signtool, it looks we cannot use Azure Trusted Signing.

Describe the solution you'd like

Add some option to sign with Azure Trusted Signing

Alternatives considered

I think it might also be good to have some option to customize command-line options for signtool or use complately custom command for code signing.

This PR will be converted into something generic before being merged #8718

At least once MS lifts the stupid 3-years tax history requirement, this should have explicit support in tauri imo (so that it's a direct config option that doesn't require the use of the generic option)
