Add ARM32 (ARMv7 hard-float) and ARM64 (AArch64) cross-compilation testing to the CI workflow. This validates that libhttpserver can be built for ARM targets using cross-compilation toolchains. Changes: - Add arm32 and arm64 matrix entries with appropriate toolchains - Add step to install ARM cross-compilation toolchains - Add separate libmicrohttpd cross-compilation steps with caching - Update configure step to use --host flag for cross-compilation - Skip tests and cppcheck for cross-compilation builds (binaries cannot execute on x86_64 runners) The existing COND_CROSS_COMPILE logic in configure.ac automatically handles test exclusion during cross-compilation. Closes #131

🚀 New features to boost your workflow:
|
The ARM cross-compiler doesn't search /usr/local by default. Install libmicrohttpd to a workspace-local sysroot and pass CPPFLAGS/LDFLAGS to libhttpserver's configure to find the headers and libraries.
