Subject: [PATCH] audioutils/lame: Add CMake vector sources.

Add the SSE2 and AVX2 vector implementation files to the CMake libmp3lame target for x86 simulator hosts. LAME's enabled runtime dispatch paths call these functions, so omitting them leaves sim:alsa with unresolved symbols at link time.

Non-x86 simulator hosts continue to use LAME's scalar implementation.
