Parser: Support multiple attribute type, reject invalid #10338

Blocker for: #9634

This pull request seeks to enhance the block parser to support multiple type, in accordance with JSON schema. This is planned to be used in #9634 to support a nullable string for align attribute, representable in JSON schema as multiple type [ "string", "null" ].

In doing so, it needs to account for how to handle existing behavior of attribute value casting, necessary for attributes sourced ambiguously as strings (e.g. as HTML attribute values). With these changes, casting only occurs for ambiguous string sources of a singular attribute type. For any other attribute, we now reject the attribute value (adopting behavior as if undefined, accounting for default value). This may be considered a breaking change, but only in cases where values were assigned of the wrong type, relying on casting to correct. More often, this should help capture unintended serialization (e.g. objects serialized as casted string [object Object]).

Testing instructions:

Verify unit tests pass.

Parser: Deprecate type coercion
It's unclear for which string sources should be considered ambiguous and allow casting, in addition to being inconsistently enforced. Rather than defaulting to leniency, we should enforce the type broadly, reintroducing leniency later if noted issues and need for multiple type support can be reconciled.
