nptl: Change tst-typesizes to _Static_assert
Instead of rely on runtime check to assure correct pthread types
size a better strategy would use _Static_assert to trigger an error
on build time (and thus allowing to check to potentially ABI breakage
on cross-compiling make check).
This patch moves nptl/tst-typesizes.c to libpthread build time on
each specific initialization routine and also remove some runtime
redundant asserts for the same type sizes.
Checked on x86_64-linux-gnu and with a build check for all affected
ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf,
hppa-linux-gnu, i686-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu, mips64-linux-gnu, mips64-n32-linux-gnu,
mips-linux-gnu, powerpc64le-linux-gnu, powerpc-linux-gnu,
s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparc64-linux-gnu,
sparcv9-linux-gnu, tilegx-linux-gnu, tilegx-linux-gnu-x32,
tilepro-linux-gnu, x86_64-linux-gnu, and x86_64-linux-x32).
