### Description

`import onnxruntime` segfaults during `dlopen` of
`onnxruntime_pybind11_state.so` on Linux. This removes the global
initializer in `onnxruntime_pybind_state.cc` that eagerly calls
`Env::Default()`, and resolves the platform `Env` on first use at its
two call sites instead.

### Motivation and Context

The module has a namespace-scope dynamic initializer:

```cpp
static Env& platform_env = Env::Default();
```

Since POSIX telemetry landed (#27379), `Env::Default()` constructs
`PosixEnv`, whose `PosixTelemetry` member initializes the 1DS SDK in its
constructor. That path reads `defaultRuntimeConfig`, a namespace-scope
`static ILogConfiguration` defined in the 1DS SDK's
`RuntimeConfig_Default.hpp`, which lives in a **different translation
unit of the same shared library**.

Dynamic initialization order across translation units is unspecified,
and the pybind TU's initializer runs first. `Variant::merge_map`
therefore iterates a still zero-initialized `std::map`: `_M_node_count
== 0`, but `_M_header._M_left` is `nullptr` rather than self-pointing,
so `begin() != end()` and the loop dereferences null.

Textbook static initialization order fiasco. Backtrace (Release build
relinked without `--strip-all` to recover symbols):

```
#0  std::map<..., Variant>::lower_bound        stl_map.h:1307
#1  std::map<..., Variant>::operator[]         stl_map.h:509
#2  Variant::merge_map                         VariantType.hpp:508
#3  RuntimeConfig_Default::RuntimeConfig_Default  RuntimeConfig_Default.hpp:97
#4  LogManagerImpl::LogManagerImpl             LogManagerImpl.cpp:183
#5  LogManagerFactory::Create                  LogManagerFactory.cpp:36
#6  LogManagerFactory::lease
#7  LogManagerFactory::Get                     LogManagerFactory.hpp:71
#8  LogManagerProvider::Get                    LogManagerProvider.cpp:16
#9  onnxruntime::PosixTelemetry::Initialize()
#10 onnxruntime::PosixTelemetry::PosixTelemetry()
#11 onnxruntime::(anonymous namespace)::PosixEnv::PosixEnv()
#12 onnxruntime::Env::Default()
#13 _GLOBAL__sub_I_onnxruntime_pybind_state.cc
#14 call_init                                  elf/dl-init.c:74
...
#21 _dl_open                                   elf/dl-open.c:905
```

The crash is independent of `LD_LIBRARY_PATH` and `CUDA_VISIBLE_DEVICES`
— it happens before any ORT runtime code runs. `libonnxruntime.so` is
unaffected because it contains no global initializer that reaches
`Env::Default()`, which is why C/C++ and onnxruntime-genai consumers do
not see it.

Both remaining uses of `platform_env` are inside pybind lambdas that run
long after load, so calling `Env::Default()` there is safe. This also
removes the now-stale `TODO: we may delay-init this variable` and a
pre-existing `#pragma warning(push)` that should have been `pop`.

Note for follow-up: `Env::Default()` is now unsafe to call from any
dynamic initializer. This was the only such call site in the tree, but
hardening `PosixTelemetry` to defer SDK initialization out of its
constructor would remove the hazard entirely.

### Tests

Verified on a Linux CUDA 13 Release build (`onnxruntime_USE_TELEMETRY`
enabled):

- `dlopen` of `onnxruntime_pybind11_state.so` succeeds (previously
SIGSEGV).
- `import onnxruntime` reports the version and
`['CUDAExecutionProvider', 'CPUExecutionProvider']`.
- `onnxruntime.enable_telemetry_events()` / `disable_telemetry_events()`
— the two call sites changed here — work.
- CPU and CUDA inference sessions produce correct results.
- Reproduced and verified with `LD_LIBRARY_PATH` unset and
`CUDA_VISIBLE_DEVICES` empty.
