This patch moves the traditional POSIX stdbool.h definitions out from
stdint.h into their own file. This helps for using these definitions in
commonlib code which may be compiled in different environments. For
coreboot everything should chain-include this stuff via types.h anyway
so nothing should change.

In general, third party code (such as vboot) doesn't know what the
underlying types are for the integers in <stdint.h>, so these macros are
useful for portably printing them. Of these definitions, coreboot so far
has only used PRIu64 (in one place), which isn't needed anymore since we
know what the underlying type of a u64 is.

There are only minimal differences between the architecture specific
stdint.h implementations, so let's tidy them up and merge them together
into a single file. In particular,
- Use 'unsigned long' for uintptr_t. This was already the case for x86
and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64
used 'unsigned long long'. This change allows using a single integer
type for uintptr_t across all architectures, and brings it into
consistency with the rest of the code base, which generally uses
'unsigned long' for memory addresses anyway. This change required
fixing several assumptions about integer types in the arm code.
- Use _Bool as the boolean type. This is a specialized boolean type that
was introduced in C99, and is preferrable over hacking booleans
using integers. romcc sadly does not support _Bool, so for that we
stick with the old uint8_t.
- Drop the least and fast integer types. They aren't used
anywhere in the code base and are an unnecessary maintenance burden.
Using the standard fixed width types is essentially always better anyway.
- Drop the UINT64_C() macro. It also isn't used anywhere and doesn't
provide anything that a (uint64_t) cast doesn't.
- Implement the rest of the MIN and MAX numerical limits.
- Use static assertions to check that the integer widths are correct.
