libyul: changing some AST members from shared_ptr<> to unique_ptr<>
...
* Some spaces look a little more verbose now, but that shouln't be a problem as it also should raise readability, too.
* This makes some use of return-value-optimizations also.

Eliminate byte-typedef and use uint8_t in all their places instead.
...
This change is made to (easily) be forward compatible with future C++
standards, in order to allow compiling the code with newer standards at
some point in the future.
* Removed the `using byte = uint8_t;` line from Common.h
* Mechanically change all uses of `byte` to `uint8_t`.
Tested with GCC 7.3 in C++11/14/17 modes :-)
