Description

Removes the PY37 flag from sentry_sdk/_compat.py, along with the code paths that only ran when it was False. It also removes the nanosecond_time() wrapper, which existed only to choose between those paths.

setup.py sets python_requires=">=3.7", so PY37 is always True on every supported interpreter, and the tox.ini matrix starts at py3.7. That makes these branches unreachable:

• nanosecond_time() in sentry_sdk/utils.py: the int(time.perf_counter() * 1e9) fallback is gone. Once only time.perf_counter_ns() was left, the wrapper added nothing, so it's removed as well. Its two call sites in sentry_sdk/traces.py (Span start and end) now call time.perf_counter_ns() directly.
• tests/test_gevent.py: compression_algo always includes "br" now, as it already did in practice.
• tests/test_transport.py: elif PY37: becomes else:, and the pre-3.7 case list after it is removed. The cases that run on 3.7 are unchanged.

PY38, PY310 and PY311 are still used, so they stay. This doesn't depend on #8153; the two only touch different lines of _compat.py and merge cleanly together.

_compat and utils are private modules, and nothing else in the repo (including tests) references nanosecond_time. Runtime behavior doesn't change on any supported Python version.
