self-hosted: rework the memory layout of ir.Module and related types

 * add TypedValue.Managed which represents a Type, a Value, and some
   kind of memory management strategy.
 * introduce an analysis queue
 * flesh out how incremental compilation works with respect to exports
 * ir.text.Module is only capable of one error message during parsing
 * link.zig no longer has a decl table map and instead has structs that
   exist directly on ir.Module.Decl and ir.Module.Export
 * implement primitive .text block allocation
 * implement linker code for updating Decls and Exports
 * implement null Type

Some supporting std lib changes:
 * add std.ArrayList.appendSliceAssumeCapacity
 * add std.fs.File.copyRange and copyRangeAll
 * fix std.HashMap having modification safety on in ReleaseSmall builds
 * add std.HashMap.putAssumeCapacityNoClobber
