Could you change bigendian to endianness everywhere? We're verifying that values are not incorrectly converted on little-endian systems as well.

There's enough test cases that this warrants being run in parallel via its own test target. Signed-off-by: Matt Leon <mattleon@google.com>
Uses bswap64 by default to handle int64 and uint64 values. For float and doubles, uses appropriate-size bswap operators by first bit-casting floats and doubles to their same-size int types. Otherwise, they will be coerced to an int type before conversion and be returned as int values. Signed-off-by: Matt Leon <mattleon@google.com>
Without first converting to uint32_t, the getters for wasm_val_t for wamr, wasmtime, and wasmedge returned a signed integer type. For uint32 values high enough to be in the negative range, sign extension would be applied when the value was coerced into proxy_wasm::Word. This resulted in Word values that did not match the comment on Word ``` // Represents a Wasm-native word-sized datum. On 32-bit VMs, the high bits are always zero. // The Wasm/VM API treats all bits as significant. ``` nor the exact value returned from the wasm plugin. Signed-off-by: Matt Leon <mattleon@google.com>

Maybe use getStatus to get uint32, string pair and test both in one go?

This test explicitly tests the bounds of various native and wasm types to ensure passing data across the ABI boundary is not lossy.
