Convert wasm-value into internal::WasmValue, then to debug::WasmValue.
This is then copied into a CDP protocol object via a new class,

a1d2e34260 [wasm][debug] Fix printing of wasm opcodes
This is a minor cosmetic fix. Wasm opcodes are bytes, hence they should
always be printed as an even number of hexadecimal digits.
Note that currently we only print a single byte anyway, but in the
future we will want to extend this to correctly parse multi-byte
opcodes. Those will also be printed as an even number of characters
then.

155d2bc4ae [wasm][debug] Add stack scope to CDP and V8
This change adds a stack scope for wasm debugging.
Currently the local scope contains both local variables as well as
the expression stack. For now, this change duplicates the information
available on stacks into the stack scope, until we have added
support for the stack scope in the DevTools front-end.

8d7747a715 [strings] Reclaim a bit in the hash field
By replacing usage of the IsNotArrayIndex bit with IsNotIntegerIndex,
we get back one bit that we can use to increase the number of hash bits
stored. The price is that strings that represent array/integer indices
beyond the cacheable range will have to be scanned more often, but these
strings should be rare, and we expect that the additional hash bit is
more worthwhile to have.

4d69c548fd [wasm][debug] Fix index-named locals
This fixes local names that are the string representation of a valid
element index.
Even though both the Liftoff and the interpreter-based test are changed,
only the latter needs to be fixed right now since Liftoff does not use
the names currently. Modifying the test just ensures that we implement
this correctly once we use the name.

Use these names to actually name the reported locals, instead of using

as fallbacks for locals which were not assigned a name.
