Update the vendored TomsFastMath (TFM) library to v0.13.1. Resolves: https://bugzilla.clamav.net/show_bug.cgi?id=11992 I removed compatibility macro's from when libTomMath was used. This required removing a bunch of faux-error handling because the fast-math equivalent functions return void, and cannot fail. The previous version used had named the header "bignum_fast.h" instead of "tfm.h" and had customizations in that header to enable TFM_CHECK all the time, and also TFM_NO_ASM if __GNUC__ not defined or if the system isn't 64bit architecture. This update uses tfm.h as-is, and has CMake define TFM_CHECK and TFM_NO_ASM as needed. I've kept bignum.h as an interface to including tfm.h so that in the future we can more easily add support for system-installed TomsFastMath instead of the vendored one, taking inspiration from Debian's patch to support system-TomsFastMath. See: https://salsa.debian.org/clamav-team/clamav/-/blob/unstable/debian/patches/add-support-for-system-tomsfastmath.patch
