More efficient parsing of JSON arrays and objects

[plokhotnyuk]

On JDK 17 it gives up to 2x times speed up on parsing of JSON arrays (see ArrayOfBooleansReading, ArraySeqOfBooleansReading, ListOfBooleansReading, VectorOfBooleansReading) and up to 1.3x times speed up on JSON objects (see GeoJSONReading) by the cost of slow down parsing of top-level JSON values (see Base64Reading, BigIntReading, IntReading, StringOfAsciiCharsReading, StringOfEscapedCharsReading, StringOfNonAsciiCharsReading)
