tint: Refactor Extensions / Enables. * Extract ast::Enable::ExtensionKind to ast::Extension. * Move the parsing out of ast::Enable and next to ast/extension.h * Change the ast::Enable constructor to take the Extension, instead of a std::string. It's the WGSL parser's responsibility to parse, not the AST nodes. * Add ProgramBuilder::Enable() helper. * Keep ast::Module simple - keep track of the declared AST Enable nodes, don't do any deduplicating of the enabled extensions. * Add the de-duplicated ast::Extensions to the sem::Module. * Remove the kInternalExtensionForTesting enum value - we have kF16 now, which can be used instead for testing. * Rename kNoExtension to kNone.

Update src/tint unittests to new @stage format. This CL updates all of the Tint unittests to the new @stage shorter syntax. This also updates the WGSL writer to emit the new short forms instead of using the deprecated form.
