py/mpconfig.h: Allow to build without alloca() for ANSI C compliance.

Define MICROPY_NO_ALLOCA=1 and memory will be allocated from heap instead
and freed by garbage collection.

// Don't use alloca calls. As alloca() is not part of ANSI C, this
// workaround option is provided for compilers lacking this de-facto
// standard function. The way it works is allocating from heap, and
// relying on garbage collection to free it eventually. This is of
// course much less optimal than real alloca().
