This CL moves switch case statements to store Expression instead
of an IntLiteralExpression. The SEM is updated to store the
materialized constant instead of accessing the expression value
directly.

In WGSL, we can shift left abstracts by >= 64, as long as the result is
representable in the data type we choose for it. When shifting 0, we can
shift by any positive u32 value (result is always 0), but in C++, it's
UB to shift by more than the bit width of the data type, so we need to
handle this. This bug was caught by ClusterFuzz.

The SwitchStatement has an IsDefault method which checks if the
condition is nullptr. The method is never called, and default
cases are tracked in the CaseStatement class, so it's questionable
what IsDefault even means here.

The reason for slow compile times is because the very large variants of
builder::Value<T>s combined with the many std::visits over these
variants result in many combinatorial instantiations of the visit
callbacks.
To address this, I added a polymorphic base class ValueBase to Value<T>,
and replaced most of the std::visit-based compile time code with runtime
virtual calls. For the two heaviest users of std::visit over the large
variants, compiles times dropped more than half (clang-10, debug):
const_eval_binary_op_test.cc: 19.079s to 7.736s
const_eval_unary_op_test.cc: 10.021s to 4.789s

For example, for-loops can declare a variable.
Change this to be a map instead of a vector. This helps with lookups.
