target-i386: introduce cpu_get_mem_attrs
Backports commit f794aa4a2fd772a3ec413c4e478cc23857cfee98 from qemu

target-i386: Fix signedness of MSR_IA32_APICBASE_BASE
Existing definition triggers the following when using clang
-fsanitize=undefined:

hw/intc/apic_common.c:314:55: runtime error: left shift of 1048575 by 12
places cannot be represented in type 'int'

Fix it so we won't try to shift a 1 to the sign bit of a signed integer.

target-i386: Move CPUX86State.cpuid_apic_id to X86CPU.apic_id
The field doesn't need to be inside CPUState, and it is not specific for
the CPUID instruction, so move and rename it.

target-i386: Eliminate cpu_init() function
Instead of putting extra logic inside cpu.h, just do everything inside
cpu_x86_init_user().

target-i386: Rename cpu_x86_init() to cpu_x86_init_user()
The function is used only for CONFIG_USER, so make its purpose clear.

target-i386: make xmm_regs 512-bit wide
Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.

This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.

The migration format is unaffected.

target-i386: Make check_hw_breakpoints static
The function is now only used from within a single file.
