Subject: [PATCH] Add FreeBSD platform support to v8 Bazel build config

Add is_freebsd config_setting to v8's Bazel config and include FreeBSD
in is_posix and is_not_android.  Wire up the FreeBSD-specific platform
source files (platform-freebsd.cc, stack_trace_posix.cc) that v8 already
ships but were not referenced from the Bazel build.  Also add a
V8_TARGET_OS_FREEBSD define and a //conditions:default fallback to the
OS-specific define select() so the build does not fail on unrecognised
platforms.
