Jon Ross-Perkins dd43bb92b5 Refactor struct literal parse nodes. (#4470) 
Split StructComma into StructLiteralComma and StructTypeLiteralComma in
order to easily differentiate handling (remains the same in this PR).

Add "Literal" to StructField and StructTypeField because it feels
inconsistent versus the other non-shared things. StructFieldDesignator
remains shared between value literals and type literals.

Note I probably would've made StructFieldDesignator non-shared too, but
that'd require either a lookahead of 2 (to see the separator`) or a
writeback after parsing the separator, neither of which felt especially
crucial for this, when what I'm really trying to do is split type
literal handling a little further.

// This is an X-macro header. It does not use `#include` guards, and instead is
// designed to be `#include`ed after the x-macro is defined in order for its
// inclusion to expand to the desired output. Macro definitions are cleaned up
// at the end of this file.
//
// Supported x-macros are:
// - CARBON_PARSE_NODE_KIND(Name)
// Used as a fallback if other macros are missing. Also, used directly
// when none of the below category-oriented macros apply.
// - CARBON_PARSE_NODE_KIND_PREFIX_OPERATOR(Name)
// Defines a parse node for a prefix operator, with the Name as token.
// - CARBON_PARSE_NODE_KIND_INFIX_OPERATOR(Name)
// Defines a parse node for an infix operator, with the Name as token.
// - CARBON_PARSE_NODE_KIND_POSTFIX_OPERATOR(Name)
// Defines a parse node for a postfix operator, with the Name as token.
// - CARBON_PARSE_NODE_KIND_TOKEN_LITERAL(Name, LexTokenKind)
// Defines a parse node that corresponds to a token that is a single-token
// literal. The token is wrapped for LexTokenKinds.
// - CARBON_PARSE_NODE_KIND_TOKEN_MODIFIER(Name)
// A token-based modifier. The Name is the TokenKind, and will be appended
// with "Modifier" for the parse kind.
//
// LexTokenKind indicates the token kind required on a valid node.
//
// Parse nodes are clustered based on language feature. See typed_nodes.h for
// the expected tree structure under each node kind.
