Mark Rutland dbc9344a68 arm64: clean up THREAD_* definitions
Currently we define THREAD_SIZE and THREAD_SIZE_ORDER separately, with
the latter dependent on particular CONFIG_ARM64_*K_PAGES definitions.
This is somewhat opaque, and will get in the way of future modifications
to THREAD_SIZE.

This patch cleans this up, defining both in terms of a common
THREAD_SHIFT, and using PAGE_SHIFT to calculate THREAD_SIZE_ORDER,
rather than using a number of definitions dependent on config symbols.
Subsequent patches will make use of this to alter the stack size used in
some configurations.

At the same time, these are moved into <asm/memory.h>, which will avoid
circular include issues in subsequent patches. To ensure that existing
code isn't adversely affected, <asm/thread_info.h> is updated to
transitively include these definitions.
