Platform::Init (now Platform::InitOnce) was only being called directly
from the CL embedder and could not be invoked via any path in the embedding
API. Platform::InitOnce is now invoked in both dart::bin::BootstrapDartIo and
dart::embedder::InitOnce.

Fixes the changes to assembly snapshot writer in SIMARM_X64 mode. This unfortunately can't be tested until the ELF loader is available.

Prior to this change, on Linux, if one created a symbolic link to the
dart executable and ran that, the kernel-service snapshot would not be
found. This has the effect of compiling the input script on a
non-trained kernel service, meaning the startup is slower.
This is particularly bad as the debian install of dart creates a symbolic
link to dart as /usr/bin/dart with the target being /usr/lib/dart/bin/dart
meaning that for instance running a hello-world script like one normally
would, `dart hello.dart` would take something along the lines of 3-4 times
longer than if running `/usr/lib/dart/bin/dart hello.dart`.
On my Pixelbook (in crostini) this is ~755 ms vs ~210 ms.
This change does *NOT* fix it on other platforms.

Since Dart 2, library prefixes are always loaded eagerly on the VM.
Also remove reload check for deferred prefixes. This check was added to avoid behavior of library prefixes giving spurious "not loaded" errors after a reload, but now this error can never occur. Resolves a difference in reload between AST and bytecode modes, since bytecode mode isn't surfacing the deferred property.

After landing d3f3b46, which adds support for vm-service to the run_vm_tests binary,
random vm/cc tests started to time out. The VM shutdown procedure waits
for the service isolate to shut down, which it doesn't do.
Since we haven't been running the vm-service isolate before, this
might've been an existing issue which is just surfaced now. This CL
disabled starting vm-service (like it was before) except for the
particular test which needs it.
