configure/swr: configurable swr architectures
Allow configuration of the SWR architecture depend libraries
we build for with --with-swr-archs. Maintains current behavior
by defaulting to avx,avx2.
Scons changes made to make it still build and work, but
without the changes for configuring which architectures.
v2:
* add missing comma for swr_archs default
* check that at least one architecture is enabled
* modify loader logic to make it clearer how to add archs
