Add addrenv support for x86_64.
For now we support mapping on PT level, so PD, PDT and PML4 are static

The new implementation support maping over 0xffffffff but requires CONFIG_MM_PGALLOC=y

Use 32bit operations for id field in intel64_cpu_s which is int type.
This fixes an error that appears when enabling some debug options:
`Error: operand size mismatch for `movq'``

Intel64 can now boot application cores which is needed for SMP
IMPORTANT: CONFIG_BOARD_LOOPSPERMSEC must be properly configured,
otherwise AP boot sequence can fail due too short delays during the AP startup

Use GS base regsiter to store reference to CPU private data.
Then we can easily refer to private CPU data using the GS segment.

Hide --whole-archive behind Kconfig option for x86.
This option is not needed and breaks ELF modules build.

on ACRN hypervisor obtaining frequency from CPUID seems to be broken,
so we have to specify this value from Kconfig.
If frequency autodetection is enabled but the returned data are
incorrect - crash early.

enable FPU and implement up_fpucmp to pass ostest
With aggressive optimization enabled (-O2/-O3), ostest FPU test will fail.
This is because the compiler will generate additional vector
instructions between subsequent up_fpucmp() calls (loop vectorization
somewhere in usleep() call), which will consequently overwrite
the expected FPU context (XMM registers).
