[Interpreter] Refactor bytecode generator test suite. Bytecode expectations have been moved to external (.golden) files, one per test. Each test in the suite builds a representation of the the compiled bytecode using BytecodeExpectationsPrinter. The output is then compared to the golden file. If the comparision fails, a textual diff can be used to identify the discrepancies. Only the test snippets are left in the cc file, which also allows to make it more compact and meaningful. Leaving the snippets in the cc file was a deliberate choice to allow keeping the "truth" about the tests in the cc file, which will rarely change, as opposed to golden files. Golden files can be generated and kept up to date using generate-bytecode-expectations, which also means that the test suite can be batch updated whenever the bytecode or golden format changes. The golden format has been slightly amended (no more comments about `void*`, add size of the bytecode array) following the consideration made while converting the tests. There is also a fix: BytecodeExpectationsPrinter::top_level_ was left uninitialized, leading to undefined behaviour.

[interpreter] Add support for scalable operands. This change introduces wide prefix bytecodes to support wide (16-bit) and extra-wide (32-bit) operands. It retires the previous wide-bytecodes and reduces the number of operand types. Operands are now either scalable or fixed size. Scalable operands increase in width when a bytecode is prefixed with wide or extra-wide. The bytecode handler table is extended to 256*3 entries. The first 256 entries are used for bytecodes with 8-bit operands, the second 256 entries are used for bytecodes with operands that scale to 16-bits, and the third group of 256 entries are used for bytecodes with operands that scale to 32-bits.
