sys/modules: fix bogus OPT_ACPI tests

ACPI is not handled specially by sys/conf/kern.opts.mk (unlike a few
options), so we should fall back on the generic behavior of
sys/conf/config.mk, which pulls from all the generated opt*.h files,
including opt_acpi.h, which will cause DEV_ACPI to be included in
KERN_OPTS. Then the generic machinery in sys/conf/kmod.mk will cause
SRCS.DEV_ACPI to be included in SRCS when appropriate.

A subsequent commit will instead use existing infrastructure to

Fix loading the hwpmc module when ACPI is enabled

In 0a9a4d2cd6092 a check for OPT_ACPI was added to the hwpmc Makefile
to fix loading the module in a kernel where ACPI has been disabled.
This broke loading the module when ACPI was enabled in the build as
OPT_ACPI isn't a Makefile macro so was always disabled.

Move this check to the C files where the DEV_ACPI macro does exist.

hwpmc: remove unused pre-table driven bits for intel

Intel now provides comprehensive tables for all performance counters
and the various valid configuration permutations as text .json files.
Libpmc has been converted to use these and hwpmc_core has been greatly
simplified by moving to passthrough of the table values.

The one gotcha is that said tables don't support pentium pro and and pentium
IV. There's very few users of hwpmc on _amd64_ kernels on new hardware. It is
unlikely that anyone is doing low level optimization on 15 year old Intel
hardware. Nonetheless, if someone feels strongly enough to populate the
corresponding tables for p4 and ppro I will reinstate the files in to the
build.

Code for the K8 counters and !x86 architectures remains unchanged.
