Daniel Leung ce44048d46 x86: rename CONFIG_SSE* to CONFIG_X86_SSE*
This adds X86 keyword to the kconfigs to indicate these are
for x86. The old options are still there marked as
deprecated.

It is possible to enable SSE without using SSE for floating
point, so fix the compiler flags.

Andrew Boie df2fe7c1f7 x86: add build system hooks for page tables
We need to produce a binary set of page tables wired together
by physical address. Add build system logic to use the script
to produce them.

Some logic for running build scripts that produce artifacts moved
out of IA32 into common CMake code.

Andrew Boie c3b3aafaec x86: generate page tables at runtime
Removes very complex boot-time generation of page tables
with a much simpler runtime generation of them at bootup.

For those x86 boards that enable the MMU in the defconfig,
set the number of page pool pages appropriately.

The MMU_RUNTIME_* flags have been removed. They were an
artifact of the old page table generation and did not
correspond to any hardware state.
