The ARM and the X86 implementation of the conversion functions share
the same, non cpu specific implementation in separate files.
This commit removes the code duplication by putting the generic
implementation into a convert_base.c, similar to to convolve_base.c

The current implementation can select the SSE support level during
compiletime only.
This commit adds functionality to automatically detect and switch
the SSE support level and automatically switch the Implementation
if the CPU does not support the required SSE level.

Patch f147b174 "sigproc: Make convolution and convert input buffers
immutable" changed the internal conversion interface with the addition
of the const type qualifier. This change was not reflected on ARM builds
which led to build failure. Add const qualifier to resolve build issue.

Complex-complex block multiples are used for phase rotation of
bursts. Optimization targeted from perf profiling.

Similar to the existing Intel SSE cases, add support for NEON vector
floating point SIMD processing. In this case, use ARM assembly
directly as the NEON intrinsics do not generate preferential code
output.
Currently support NEON vectorized convolution and floating point
integer conversions.
