RFR: 8255255: Update Apache Santuario (XML Signature) to version 2.2.0 [v2]

[Weijun Wang]

> This is a multi-commits PR that upgrades xmldsig to be equivalent to Santuario 2.2.0.
> 
> The first step is an auto-import. The JDK implementation is removed first and Santuario code are imported. Some unrelated files (Ex: encryption) are removed, and package names are renamed to be internal. There are also some bulk changes on company name, comment style, and white spaces.
> 
> Next steps are patches applied by JDK. Some are old patches before the last import. Some are new.
> 
> Several tests need to be updated because of internal method signature changes.
> 
> The "Support RSA-PSS with parameters" commit introduces a new public API and would need a CSR.
> 
> The last patch is one we just fixed several days ago.
