build: set v8_enable_webassembly=false when lite mode is enabled

We should set v8_enable_webassembly=false when lite mode is enabled,
since v8_enable_lite_mode implies v8_jitless, and wasm currently
doesn't work with jitless. This is automatically handled in gn, but
seems to be not the case in gyp. Enabling lite mode without setting
v8_enable_webassembly=false leads to "Warning: disabling flag
--expose_wasm due to conflicting flags" at runtime.
