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

This changes the parsing grammar and validation rules to more correctly implement the current state of the GraphQL SDL proposal (facebook/graphql#90)

BREAKING CHANGE: SchemaBuilder::build() and buildAST() and constructor
removed the typedecorator, as not needed anymore as library can now resolve
union and interfaces from generated schemas.
* 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'

As discussed in facebook/graphql#90
This proposes replacing leading comment blocks as descriptions in the schema definition language with leading strings (typically block strings).
While I think there is some reduced ergonomics of using a string literal instead of a comment to write descriptions (unless perhaps you are accustomed to Python or Clojure), there are some compelling advantages:
* Descriptions are first-class in the AST of the schema definition language.
* Comments can remain "ignored" characters.
* No ambiguity between commented out regions and descriptions.
Specific to this reference implementation, since this is a breaking change and comment descriptions in the experimental SDL have fairly wide usage, I've left the comment description implementation intact and allow it to be enabled via an option. This should help with allowing upgrading with minimal impact on existing codebases and aid in automated transforms.
BREAKING CHANGE: This does not parse descriptions from comments by default anymore and the value of description in Nodes changed from string to StringValueNode
specification.
The framework currently coerces query variables similar to the way it
treats output values, which means it attempts to coerce the value into
the field's corresponding data type regardless of the received value.
According to items 3f and 3g in section 6.1.2
(http://facebook.github.io/graphql/#sec-Validating-Requests) of
Facebook's GraphQL specification query variables should be coerced
according to their type's input coercion rules laid out in section
3.1.1 (http://facebook.github.io/graphql/#sec-Scalars). If the value
can not be coerced into the correct type according the the input
coercion rules for the type a query error should be thrown. This
ensures that client provided query variables were of the correct format
and will be a valid format and type by the time they are passed into an
implementing resolver.
This patch fixes the above issue by updating the way query variables
are sanitized during the process of parsing the query. It directly
follows the rules for scalar input coercion laid out by the
specification and throws query errors when a value that cannot be
coerced to the correct type is given. Tests for isValidPHPValue will
also be updated to ensure that it is doing the correct type checks on
Values::isValidPHPValue for the given type and value provided. A new
test case will also be added to test Values::getVariableValues and make
sure it is also enforcing the scalar input coercion rules and throwing
errors for invalid values.
