fix(swc): suppress swc output by default

[mattem]

By default, swc outputs Successfully compiled 1 file with swc. when compilation is successful, this extra logging isn't really needed under bazel, and leads to polluted logs when many swc rules are used.

Add the -q flag by default to quieten down the output, errors will still be printed:

$ bazel build //examples/simple:transpile
