Damien George 5ffe1d8dc0 py/gc: Add MICROPY_GC_CONSERVATIVE_CLEAR option to always zero memory. 
There can be stray pointers in memory blocks that are not properly zero'd
after allocation.  This patch adds a new config option to always zero all
allocated memory (via gc_alloc and gc_realloc) and hence help to eliminate
stray pointers.

See issue #2195.
