Added support for record and tuple syntax. (#10865)

* Added support for record and tuple syntax.

This commit adds support for both the hash #{} and bar {||}
syntaxes to babel-parser, as well as adds the supporting
babel-plugin-syntax-record-and-tuple plugin to enable support
for the syntax. Does not include any transform for records and
tuples.

* typo

* added check to ensure recordAndTuple in babel-parser

* switched to syntaxType option instead of explicit entries for each record and tuple type

* switched to using recordAndTupleSyntaxType for generator options instead of adding to node

* added tests for generator option recordAndTupleSyntaxType

* added test for record and tuple bar syntax with flow typings

* added tests for invalid/missing recordAndTuple syntaxType parser option

* fixed flowcheck errors

* fix merge with class privates in tokenizer

* Update packages/babel-parser/src/types.js
