feat envoy: Force building WASM in standalone mode.

vchigrin · Kamil Khamitov · commit 1c0a82b06d37 · 2025-03-03T15:41:29.000+03:00
Without this define some third-party libraries, e.g. absl, use EM_JS macro to generate code, that requires JS runtime from WASM host.
With current build configuration it results in unresolved imports in produced .wasm file.
