Fixed #2215 - Support BigInteger and BigDecimal in StdValueInstantiator

[upsidedownsmile]

(for #2215)

• Add BigInteger creator to StdValueInstantiator#createFromInt, StdValueInstantiator#createFromLong StdValueInstantiator#createFromDouble for the case that number type is INT, LONG and DOUBLE respectively.
• Created StdValueInstantiator#createFromBigInteger and StdValueInstantiator#createFromBigDecimal and auxiliary methods(canCreateFrom..., configureFrom...) for the remaining cases, when number type is BIG_INTEGER and BIG_DECIMAL.
• Get the single argument creator inside BasicDeserealizerFactory#_handleSingleArgumentCreator and add C_BIG_INTEGER and C_BIG_DECIMAL types to CreatorCollector to represent each one.

Sounds good -- thank you very much for contributing this!

I need to re-read it once to see if I missed anything, but one thing I do need before merging is CLA from:

https://github.com/FasterXML/jackson/blob/master/MANUAL.md

and the common way is to print it, fill & sign, scan/photo, email to info at fasterxml dot com.
This only needs to be done once, before the first contribution.

Looking forward to merging this PR, thank you again!

... and here we have a bug.

Which is not caught by test cases since numbers used do not extend beyond value range of long (for BigInteger), or, for BigDecimal as that is never really reported by JSON parser. Would be exposed by Smile codec, maybe some other binary codecs.
But I'll try fixing BigInteger case at least.
