Splits IR files into SemIR, and logic files into Check. These will be split into separate directories as part of a later move; the namespaces are being done first in order to vet the switch, and hopefully make conflicts a little easier to manage due to the substantial renames. A lot of this is just automated removal of Semantics prefixes from names, adding namespace references where needed. A few special-cases are: - SemanticsIR -> SemIR::File - A few things were discussed, like Unit, CompileUnit, or CompiledUnit. Unit was too vague for chandlerc, and I thought CompileUnit might lead to incorrect inferences (CompilationUnit would be more precise, but typically written as SemIR::CompilationUnit which is pretty long). File seemed to be a short name that we could agree on. - SemanticsIRFormatter -> SemIR::Formatter - FormatSemanticsIR -> SemIR::FormatFile - SemanticsFileTest -> CheckFileTest - It remains in the Testing namespace, where just "FileTest" might be too broad a name. - SemanticsDeclarationNameStack::Context -> Check::DeclarationNameStack::NameContext - This avoids a Check::Context name shadowing. Changes check_internal.h to include ostream.h to improve finding of Print/operator<< (otherwise it didn't compile). This is part of #3070
