build,win,v8: allow precompiling objects-inl.h

This makes compiling v8_base much faster on Windows.

Sharding is disabled because the header would have to be precompiled
for each shard but is only once. The library is much smaller, so
sharding is unnecessary.

This is enabled by default, but disabled for CI and releases.
