Implement more ServicePoint properties

[liveans]

This PR implements:
HttpWebRequest:

• DefaultMaximumErrorResponseLength

ServicePoint:

• BindIPEndPointDelegate
• ProtocolVersion
• UseNagleAlgorithm
• Certificate

ServicePoint but no effect (We're creating a new handler for every request if we have non-null ServicePoint):
These properties will matter in case we want to invest some work in caching of HttpClient under HttpWebRequest, the current implementation is straightforward and these properties are not gaining any advantage from it.

• ConnectionLimit
• MaxIdleTime
• ConnectionLeaseTimeout

Maybe I can implement the IdleSince property from ServicePoint by using PlaintextStreamFilter.

PlaintextStreamFilter=(context,ct)=>{ServicePoint.IdleSince=DateTime.Now;returnValueTask.FromResult(context.PlaintextStream);}

But not sure if this is a good idea, any suggestions @dotnet/ncl ?

Left a couple questions + style changes, otherwise this looks good
