d8 treats files with the .mjs extension as modules instead of
classic scripts. Thus, the `// MODULE` pragma and its corresponding
logic in test runners can be removed in favor of explicitly adding
the extension.

Declare Variables with a name and position, rather than by passing
through a VariableProxy. This allows us to not create dummy proxies
for things like function declarations, and allows us to consider those
declarations unused.
As a side-effect, we also have to check if a variable is unused in the
bytecode generator (as it will no longer be allocated), and we end up
skip generating code/SFIs for dead variables/functions.

Since it's explicit what we're tracking, we can immediately throw errors in
certain cases, and ignore irrelevant errors. We don't need to use the
classifier itself to track "let let", since we know whether we're parsing a
"let". Errors that were previously (almost) always accumulated are now
immediately pushed to the scopes that care (parameter initialization errors).
This CL drops avoiding allocation of classified errors, at least for now, but
that doesn't affect performance anymore since we don't aggressively blacklist
anymore. Classified errors are even less likely with the more precise approach.
ParseAssignmentExpression doesn't introduce its own scope immediately, but
reuses the outer scope.
Rather than using full ExpressionClassifiers + Accumulate to separate
expressions/patterns from each other while keeping track of the overall error
state, this now uses an explicit AccumulationScope.
When we parse (async) arrow functions we introduce new scopes
that track that they may be (async) arrow functions.
We track StrictModeFormal parameters in 2 different ways if it isn't
immediately certain that it is a strict-mode formal error: Either directly on
the (Pre)ParserFormalParameters, or on the NextArrowFunctionInfo in the case
we're not yet certain that we'll have an arrow function. In the latter case we
don't have a FormalParameter object yet, and we'll copy it over once we know
we're parsing an arrow function. The latter works because it's not allowed to
change strictness of a function with non-simple parameters.

the failure message is (sometimes) being printed.
After this refactoring, we can write tests for our mjsunit test
