* Move collapse(expansions:for:attachedTo:) to SwiftSyntaxMacroExpansion * SwiftSyntaxMacroExpansion.expandAttachedMacro() now perform collapsing * SwiftSyntaxMacroExpansion.expandAttachedMacroWithoutCollapsing() to keep old behavior * IPC request 'getCapability' now sends the host protocol version * Unified IPC response 'macroExpansionResult' that returns single string for both 'expandFreestandingMacro' and 'expandAttachedMacro' * Compiler accepts old 'expandFreestandingMacroResult' and 'expandAttachedMacroResult' to keep compatibility * Plugins check the compiler's protcol version to see if it suppports 'macroExpansionResult', and fall back to old behavior if necessary
