tint: Add enable directive for extensions In this CL the enable directive is implemented. 1. Add AST node for enable directive, assign a ExtensionKind (enum) for each supported extension. 2. Use an unorder_set in ast::Module to record all required extensions' kind. 3. Provide inspector methods for getting names of used extension, and getting all used enable directives' extension names and location. 4. For different writer, the extension nodes are handled in different ways. MSL and HLSL writers will just ignore the extension nodes, while SPIRV and GLSL writers will emit corresponding code. 5. Implement unittests and end2end test for enable directive and inspector, using a reserved extension name `InternalExtensionForTesting`.

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.
