Add two experimental config options: MLD_CONFIG_ALIGN sets the alignment of large buffers and structures in bytes, MLD_CONFIG_ALIGN_ATTRIBUTE replaces the declarator prefix for compilers whose spelling mldsa-native does not know. MLD_DEFAULT_ALIGN, MLD_ALIGN and MLD_ALIGN_UP derive from them. The x86_64 and AArch64 backends reject an alignment below what their load and store instructions require. MLD_TOTAL_ALLOC_* is measured for the default alignment, so it is no longer defined once the alignment is customized, and the allocation test skips itself in that case. - Partially addresses #1346 Signed-off-by: Matthias J.
