The wasm decoder immediates are currently templatized by the {validate}
enum value. They do not need to be though; the only difference is in the
constructor, so the constructor should be templatized instead.
This CL implements that, and also changes the {validate} enum to be a
tag (a typename) instead. This is needed in order to enable template
parameter deduction for the constructor calls (C++ does not allow to
explicitly define the template parameter at constructor calls).
As a nice side effect, this produces nicer symbolized stack traces.
Before:
v8::internal::wasm::Decoder::read_u32v<(v8::internal::wasm::Decoder::ValidateFlag)1>
After:
v8::internal::wasm::Decoder::read_u32v<v8::internal::wasm::Decoder::BooleanValidationTag>
