Move wrappers to libm-compat-calls-auto
This commit moves one step towards the deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality, by adding the suffix '_compat' to their filenames and adjusting Makefiles and #includes accordingly. New template wrappers that do not use such functionality will be added by future patches and will be first used by the float128 wrappers.
