Adrian Prantl 84fdfb9ca6 [lldb] Store expression evaluator diagnostics in an llvm::Error (NFC) (#106442) ...

…NFC]

This patch is the first patch in a series reworking of Pete Lawrence's
(@PortalPete) amazing proposal for better expression evaluator error
messages (https://github.com/llvm/llvm-project/pull/80938)

This patch is preparatory patch for improving the rendering of
expression evaluator diagnostics. Currently diagnostics are rendered
into a string and the command interpreter layer then textually parses
words like "error:" to (sometimes) color the output accordingly. In
order to enable user interfaces to do better with diagnostics, we need
to store them in a machine-readable fromat. This patch does this by
adding a new llvm::Error kind wrapping a DiagnosticDetail struct that
is used when the error type is eErrorTypeExpression. Multiple
diagnostics are modeled using llvm::ErrorList.

Right now the extra information is not used by the CommandInterpreter,
this will be added in a follow-up patch!
