build: do not include shared gtest in node link path

[aduh95]

gtest symbols are only used by cctest, but atm ./configure --shared-gtest results in -lgtest being added for all compilation, which results in readelf -d bin/node listing NEEDED libgtest.so. This PR introduces a separate node_shared_gtest_libraries list that is only provided to cctest recipe

@nodejs/quic looks like we're broken on main, likely due to the V8 upgrade:

../src/quic/application.cc:159:12: error: no member named 'SetPrototypeV2' in 'v8::Object'; did you mean 'SetPrototype'?
