Summary [CMake] Build Fix Undefined symbol bssl::CloseFD when linking WebCore

315200@main added third_party/boringssl/src/tool/internal.h to the libwebrtc prefix header as part of an auto-generated list of headers used by >= 15 files. That header belongs to the BoringSSL command-line tool, not the library: it declares ScopedFD, whose inline reset() calls bssl::CloseFD(), which is only defined in tool/fd.cc -- a file never compiled into libwebrtc. Pulling it into the PCH caused ScopedFD::reset() to be emitted as a weak symbol referencing the missing CloseFD, producing an undefined-symbol error when linking WebCore. No library source actually includes tool/internal.h or uses ScopedFD, so remove it from the prefix header.
