Allow MacOS sudo to be bypassed

• Operating System: MacOS 15.1

Description

Currently, when sudo is available on MacOS, I believe it is unavoidable that powermetrics.is_powermetrics_available() will attempt to use it, even if a default power is supplied.

Although ways to avoid the need for sudo entirely would be significantly more useful (e.g. discussion in #731), a simple short term solution could be to swap the current check:

powermetrics.is_powermetrics_available() and self._default_cpu_power is None

If instead the check against _default_cpu_power is performed first, this would enable avoiding the need to call powermetrics.is_powermetrics_available().

It may also be more efficient to swap this check for other branches of if statements, although I haven't encountered specific issues. (There's also cpu.is_rapl_available(), which doesn't check whether self._default_cpu_power is None. This seems inconsistent, but it may be intentional?)

What I Did

from codecarbon import OfflineEmissionsTracker
from codecarbon.external.hardware import POWER_CONSTANT

OfflineEmissionsTracker(
    country_iso_code="GBR",
    default_cpu_power=POWER_CONSTANT,
    log_level="DEBUG",
)

This currently prompts for a password, even when the supplied default will be used.
