rpc: Accept scientific notation for monetary amounts in JSON
Add a function `ParseFixedPoint` that parses numbers according
to the JSON number specification and returns a 64-bit integer.
Then this in `AmountFromValue`, rather than `ParseMoney`.
Also add lots of tests (thanks to @jonasschnelli for some of them).
Fixes issue #6297.
