build: use allowed over enabled

Meson feature options are typically in a tri-state of enabled, disabled,
or auto. The enabled and disabled functions on an option (from
`get_option`) no longer return true for auto features. Instead, the
expectation is to use `allowed()` which is true for both enabled and auto.

Switch all uses of `enabled` to `allowed`.

Implementing the TempToMargin feature

Wrapping the input name std::string in a new structure SensorInput, so
that the TempToMargin information can be cleanly carried along with
it, all the way down to the PID input processing layer where it is
needed. This allows the conversion to be done just-in-time before the
temperature reading is interpreted, minimizing the blast radius of
this change. Nonetheless, because of the type change, there was a
somewhat large blast radius to implement this feature.

The design, and the documentation, is already here:
https://github.com/openbmc/phosphor-pid-control/issues/23

Tested: Added unit tests for JSON parsing and for proper execution
of the TempToMargin feature. They pass. Ran it locally, on our
appropriately-configured system, and it seems to work for me.

Adding new feature of core PID loop logging

This differs from the normal logging,
as this focuses on the core of the PID loop computations.

All variables within the core pid/ec/pid.cpp pid()
function are now logged, so math can be debugged.

Output is throttled to only log a new line
when it changes, or when 60 seconds have elapsed.

Creates 2 files for each PID loop,
one showing coefficients that were configured for it,
and one showing the variables changing over time.

Enable by --corelogging command line option,
or by creating /etc/thermal.d/corelogging file.

Tested:
Log files appear as expected, when enabled.
No changes noticed, when this feature is disabled.
