linuxkpi: Introduce module_param() of type `bint`

In Linux, this limits the accepted value to -1, 0 and 1.
In FreeBSD, this remains a signed integer with no specific constraints.

This change is a requirement to update our DRM drivers to Linux 5.12.

linuxkpi: Introduce module_param() of type `hexint`

In Linux, this affects how the value is formatted. In FreeBSD, this

Add support for runtime modifiable module parameters in the LinuxKPI.

Linux module parameters have a permissions value. If any write bits
are set we are allowed to modify the module parameter runtime. Reflect
this when creating the static SYSCTL nodes.

Implement Linux module parameters as read-only tunable SYSCTLs.

Bool module parameters are no longer supported, because there is no
equivalent in FreeBSD.

There are two macros available which control the behaviour of the
LinuxKPI module parameters:

- LINUXKPI_PARAM_PARENT allows the consumer to set the SYSCTL parent
where the modules parameters will be created.

- LINUXKPI_PARAM_PREFIX defines a parameter name prefix, which is
added to all created module parameters.

Finish process of moving the LinuxKPI module into the default kernel build.

- Move all files related to the LinuxKPI into sys/compat/linuxkpi and
its subfolders.
- Update sys/conf/files and some Makefiles to use new file locations.
- Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn
adds the LinuxKPI to all LINT builds.
- The LinuxKPI can be added to the kernel by setting the
COMPAT_LINUXKPI option. The OFED kernel option no longer builds the
LinuxKPI into the kernel. This was done to keep the build rules for
the LinuxKPI in sys/conf/files simple.
- Extend the LinuxKPI module to include support for USB by moving the
Linux USB compat from usb.ko to linuxkpi.ko.
- Bump the FreeBSD_version.
- A universe kernel build has been done.
