emscripten options should be in the compile and link command

Describe Bug

For compiler options to be handled properly by emcc/em++, same options must be used at compile and link.

Here, an explanation about the optimization options: https://emscripten.org/docs/compiling/Building-Projects.html?highlight=optimization#building-projects-optimizations

$ xmake
emcc -c -O2 -o build/.objs/test/wasm/wasm32/release/test.cpp.o test.cpp
em++ -o build/wasm/wasm32/release/test.html build/.objs/test/wasm/wasm32/release/test.cpp.o

-O2 is missing on em++ ...

Expected Behavior

$ xmake
emcc -c -O2 -o build/.objs/test/wasm/wasm32/release/test.cpp.o test.cpp
em++ -O2 -o build/wasm/wasm32/release/test.html build/.objs/test/wasm/wasm32/release/test.cpp.o

-O2 on both lines.

Project Configuration

test.cpp

#include <cstdio>
int main() { puts("Hello"); }

xmake.lua

set_optimize("faster") -- enable -O2

target("test")
    set_kind("binary")
    add_files("test.cpp")
