Use wasm for all production build profile builds

[kanej]

There are some builds of solc that produce subtly different bytecode depending on the platform they are running on.
When running under the production build profile, we should force compilation through the wasm version of solc to isolate us from the underlying platform.

In the light of #6336, this might not always be possible.

In particular, the solcjs-wrapper stores the compiler output from solcjs as a string, and so does our solcjs-runner. For very large codebases, the string containing the compiler output might exceed the maximum string length.

Line 31 in 942d9af

const output = solc.compile(input);

This is not a problem for the native compilers because we now handle their outputs as streams instead - #6411
