This generalizes the "arguments of correct type" and "default values of correct type" to a single rule "values of correct type" which has been re-written to rely on a traversal rather than the utility function `isValidLiteralValue`. To reduce breaking scope, this does not remove that utility even though it's no longer used directly within the library. Since the default values rule included another validation rule that rule was renamed to a more apt "variable default value allowed".
This also includes the original errors from custom scalars in the validation error output, solving the remainder of graphql/graphql-js#821.

This is a fairly major refactoring of coerceValue which returns an Either so it can return a complete collection of errors. This allows originalError to be preserved for scalar coercion errors and ensures *all* errors are represented in the response.
This had a minor change to the logic in execute / subscribe to allow for buildExecutionContext to abrupt complete with multiple errors.

This moves validation out of GraphQLSchema's constructor (but not yet from other type constructors), which is responsible for root type validation and interface implementation checking.
Reduces time to construct GraphQLSchema significantly, shifting the time to validation.
This also allows for much looser rules within the schema builders, which implicitly validate while trying to adhere to flow types. Instead we use any casts to loosen the rules to defer that to validation where errors can be richer.
This also loosens the rule that a schema can only be constructed if it has a query type, moving that to validation as well. That makes flow typing slightly less nice, but allows for incremental schema building which is valuable
ref: graphql/graphql-js#1124
This factors out the enum value validation from scalar value validation and ensures the same try/catch is used in isValidLiteralValue as isValidPHPValue and protecting from errors in valueFromAST.
ref: graphql/graphql-js#1126
This changes the parsing grammar and validation rules to more correctly implement the current state of the GraphQL SDL proposal (facebook/graphql#90)
ref: graphql/graphl-js#1102
This changes the check for null/undefined to a check for undefined to determine if scalar serialization was successful or not, allowing `null` to be returned from serialize() without indicating error.
This is potentially breaking for any existing custom scalar which returned `null` from `serialize()` to indicate failure. To account for this change, it should either throw an error or return `undefined`.
ref: graphql/graphql-js#1104
* Generalizes building a value from an AST, since "scalar" could be misleading, and supporting variable values within custom scalar literals can be valuable.
* Replaces isNullish with isInvalid since `null` is a meaningful value as a result of literal parsing.
* Provide reasonable default version of 'parseLiteral'
