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.

tint/writer/spirv: Support for F16 type, constructor, and convertor This patch make SPIRV writer support emitting f16 types, f16 literals, f16 constructor and convertor. Unittests are also implemented. Currently SPIRV writer will require 4 capabilities in generated SPIRV: `Float16`, `UniformAndStorageBuffer16BitAccess`, `StorageBuffer16BitAccess`, and `storageInputOutput16`.
