fix(smol): prevent abseil duplicate symbols on Windows

Disables standalone abseil.lib build on Windows by changing the abseil
target type from 'static_library' to 'none'. This prevents LNK2005
linker errors where absl::Mutex::Dtor and other symbols are defined
in both abseil.lib and v8_libbase.lib.

Root cause: Node.js v24 extracted abseil to a separate build target
(tools/v8_gypfiles/abseil.gyp) to share code between V8 and perfetto.
On Windows with MSVC, this creates duplicate symbol errors because
V8's libbase already includes the necessary abseil implementations.

Solution: On Windows only, configure abseil as type 'none' so headers
are available but no separate static library is built. V8's libbase
continues to provide the abseil implementations it needs.

Error: abseil.lib(abseil.mutex.obj) : error LNK2005: absl::Mutex::Dtor
already defined in v8_libbase.lib(v8_libbase.mutex.obj)
