treewide: cpufreq: Remove interactive cpufreq governor

The interactive cpufreq governor is incompatible with the latest stable Linux branch (v6.1.138) and is no longer maintained.
Remove it instead of updating for Linux 6.1 compatibility.

-``interactive``
-----------------
-
-The CPUfreq governor `interactive` is designed for latency-sensitive,
-interactive workloads. This governor sets the CPU speed depending on
-usage, similar to `ondemand` and `conservative` governors, but with a
-different set of configurable behaviors.
-
-The tunable values for this governor are:
-
-``above_hispeed_delay``
-        When speed is at or above hispeed_freq, wait for
-        this long before raising speed in response to continued high load.
-        The format is a single delay value, optionally followed by pairs of
-        CPU speeds and the delay to use at or above those speeds.  Colons can
-        be used between the speeds and associated delays for readability.  For
-        example:
-
-           80000 1300000:200000 1500000:40000
-
-        uses delay 80000 uS until CPU speed 1.3 GHz, at which speed delay
-        200000 uS is used until speed 1.5 GHz, at which speed (and above)
-        delay 40000 uS is used.  If speeds are specified these must appear in
-        ascending order.  Default is 20000 uS.
-
-``boost``
-        If non-zero, immediately boost speed of all CPUs to at least
-        hispeed_freq until zero is written to this attribute.  If zero, allow
-        CPU speeds to drop below hispeed_freq according to load as usual.
-        Default is zero.
-
-``boostpulse``
-        On each write, immediately boost speed of all CPUs to
-        hispeed_freq for at least the period of time specified by
-        boostpulse_duration, after which speeds are allowed to drop below
-        hispeed_freq according to load as usual. Its a write-only file.
-
-``boostpulse_duration``
-        Length of time to hold CPU speed at hispeed_freq
-        on a write to boostpulse, before allowing speed to drop according to
-        load as usual.  Default is 80000 uS.
-
-``go_hispeed_load``
-        The CPU load at which to ramp to hispeed_freq.
-        Default is 99%.
-
-``hispeed_freq``
-        An intermediate "high speed" at which to initially ramp
-        when CPU load hits the value specified in go_hispeed_load.  If load
-        stays high for the amount of time specified in above_hispeed_delay,
-        then speed may be bumped higher.  Default is the maximum speed allowed
-        by the policy at governor initialization time.
-
-``io_is_busy``
-        If set, the governor accounts IO time as CPU busy time.
-
-``min_sample_time``
-        The minimum amount of time to spend at the current
