* chore: adopt nodejs/node#66752 in BoringSSL node patch

Rework fix_handle_boringssl_and_openssl_incompatibilities.patch to carry
the OPENSSL_SIZE_T changes from nodejs/node#66752
verbatim instead of Electron's own size_t edits, so the patch drops out
cleanly once Electron updates to a Node.js version that includes it.

Also drop the `#if 0` guards in src/node_metadata.h and
src/node_options.h, restoring upstream's `#if HAVE_OPENSSL`. BoringSSL
provides the OpenSSL headers they include and the quic guard keeps
openssl/quic.h out, so the guards are no longer needed.

* fix: add BoringSSL include path to node snapshot targets

With the `#if 0` guards gone, src/node_options.h and src/node_metadata.h
include <openssl/opensslv.h> and <openssl/crypto.h> again whenever
HAVE_OPENSSL is set. The :node_snapshot and :node_snapshot_stub source
sets get HAVE_OPENSSL=1 from :node_internal_config but did not depend on
//third_party/boringssl, so they had no BoringSSL include path and the
Windows build failed with "'openssl/opensslv.h' file not found" when
compiling node_snapshot.cc.

Depend on //third_party/boringssl from both targets when
node_use_openssl is set, so they see the same headers as libnode.

* chore: use $node_openssl_path for node snapshot OpenSSL dep

Depend on "$node_openssl_path" rather than hard-coding
//third_party/boringssl in the :node_snapshot and :node_snapshot_stub
targets, matching how upstream's unofficial.gni references OpenSSL.
Electron sets node_openssl_path = "//third_party/boringssl" in
build/args/all.gn, so the resolved dependency is unchanged.
