Document `StreamReadConstraints`, `StreamWriteConstraints` on Wiki

[cowtowncoder]

So, would be good to fill these 2 Wiki pages:

• https://github.com/FasterXML/jackson-core/wiki/StreamReadConstraints
• https://github.com/FasterXML/jackson-core/wiki/StreamWriteConstraints

with basic listing of available options; copy-pasted from Javadocs as necessary.
