Daniel Lehmann e28d3d191d [wasm] fix printing of float literals in disassembler 
Previously, some float literals were printed with loss of information by
the Wasm disassembler, e.g., `1234567.5` was printed as `1234568`,
which is clearly wrong.

With this fix, the disassembler will always preserve information in its
output, i.e., it will print the correct `1234567.5`.
However, unfortunately, it will now print the binary representation of
`0.1` as `0.100000001`, since 0.1 can actually not be represented
exactly as a binary fraction.
Ideally, we would print the smallest representation of a float that,
when parsed again (e.g., by `wat2wasm`), produces the same float.
Unfortunately, there is currently no easy way to implement this.

There are several options, but they are either incorrect in other ways
or not available here:
- `DoubleToCString`: output will be even longer for decimal fractions
that cannot be represented in binary, since it will just round to the
nearest double instead.
- `printf` + `%g` format specifier: still prints `0.1` as `0.100000001`.
- `std::format`: C++20 only.
- `std::to_char`: C++17, but this particular header is not yet allowed.
- `absl::to_char`: Abseil is not available in V8.

It seems we have to choose either between losing information (such that
the output of the disassembler would not round-trip if assembled to a
binary again), or to have those ugly, long outputs.
