src: do not expose simdjson.h in node_config_file.h

[zcbenz]

It is not needed, and on Windows files including the header needs some other configs otherwise errors like this may happen:

../../node/deps/simdjson/simdjson.h(12949,7): error: implicitly declaring library function '_BitScanReverse64' with type 'unsigned char (unsigned long *, unsigned long long) noexcept' [-Werror,-Wimplicit-function-declaration]
 12949 |   if (_BitScanReverse64(&leading_zero, input_num))
       |       ^
../../node/deps/simdjson/simdjson.h(12949,7): note: include the header <intrin.h> or explicitly provide a declaration for '_BitScanReverse64'
1 error generated.
