Martin Kustermann 168539d61d Reland "[vm] Build dart2native dependencies with the normal "create_sdk" target"
The flutter engine DEPS got new icu/boringssl so this CL can safely
land and roll into engine. A small change is made in Patchset 1..3.

This removes special logic for creating the `dart-sdk` we distribute
which used to build release and product mode and copied some binaries
from the latter into the former, before the SDK was actuallly ready to
test and distribute.

This changes the GN build rules to build the necessary
gen_snapshot/dart_precompiled_runtime product binaries during the normal
release build.

Normally during --mode=product builds the global build config in
//build/config/BUILDCONFIG.gn will set `-fvisibility=false`.

=> Doing so results in much smaller binaries - because only explicitly
   exported symbols are visible, the rest can be tree shaken by the linker.

Since we are building --mode=release, the `-fvisibility=false` will not
be set. In order to set the flag for the 2 special product-mode binaries
we need to add -fvisibility=hidden manually, in:

  * dart_product_config: Which is used for compiling VM sources.
  * 3rd party double-conversion library
  * 3rd party boringssl library
  * 3rd party icu library

The upstream CLs are:

  * BoringSSL: https://dart-review.googlesource.com/c/boringssl_gen/+/150482
  * ICU: https://chromium-review.googlesource.com/c/chromium/deps/icu/+/2236407
