fix(connection): bump websocket max received message size to 256Mb (#4571)
This is the max message size that DevTools can emit over the DevTools
protocol: https://cs.chromium.org/chromium/src/content/browser/devtools/devtools_http_handler.cc?type=cs&q=kSendBufferSizeForDevTools&sq=package:chromium&g=0&l=83

Test is failing on firefox since Firefox crashes when allocating 100Mb string.

Fix #4543
