Introduce the initial changes needed to get other processors up and into kernel mode.
This only supports x86 as of now but is the first real step towards using other system processors.
This will be needed for compatibility with x86 Windows Vista/7 videoprt.sys builds.
Might be also useful in future for platforms (x86 , ...) where V86 mode is not available or buggy.

This allows to somewhat reduce their size, and the resulting size
of the generated hal.dll file.

Only done in our own code, not in 3rd-party or in PSDK headers
(official ones also have such typos in defines...)
(NOTE: apparent "Uknown" typo in dll/cpl/sysdm/smbios.c is on-purpose:
typo by the manufacturer.)
- Remove ContextValue variable. This variable erroneously truncated
*Context value (that can contain a pointer value) to 32 bits.
- Gracefully fail instead of asserting.

Use an INT call stub and exit on the address after the stub instead or using iret (some BIOS code uses int / iret internally). This fixes the messed up display when trying to switch modes.
Reference: https://wiki.osdev.org/PCI#Address_and_size_of_the_BAR
To determine the amount of address space needed by a PCI device,
you must save the original value of the BAR, write a value
of all 1's to the register, then read it back.
Note: 64-bit BARs are not supported yet.
Fixes compilation because the Hal(Private)DispatchTable's, defined in
the bootloader's NTOS stub, are not external imports, as they would be
for a standard HAL.
This also removes the following warnings, that were present because,
as the ACPICA acpi.h header was used as PCH (instead of none, or the
hal's own main header), it was "included" before any other header
-- and in particular, before hal.h -- and as a result, colliding defines
were still defined even if the #undef tricks were used for them.

The HalpBiosDisplayReset() function is currently stub-plemented.
Returning FALSE will make bootvid take the route of fully
re-initializing the VGA display all by itself.
Simplify code, instead of adding 2 missing ObDereferenceObject().
(Note that ObInsertObject() always dereferences the object in case of failure.)
CORE-17904
The interval time is now calculated in 0.1ns precision and a running fraction on the 100ns interval is updated on each clock interrupt.
Also adjust minimum, maximum and default clock rate to what Windows uses.
Previously we enabled the timer interrupt, before the kernel was notified of our time increment, so when a clock interrupt happened, it would increment the tick count, but add 0 to the system time, resulting in an invalid state, in which timers would be inserted into the wrong timer table slot. Fixes CORE-16253
