qemu/main: Make GC heap size configurable on a per-arch basis.

Browse Source 
In certain circumstances depending on the code size, the
`deflate_decompress` test fails on both ARM and RV32 with a memory
allocation failure error.  The issue is mitigated by having a larger GC
heap, in this case around 20 KBytes more than the original 100 KBytes
default.

This commit makes the GC heap size configurable on a per-arch basis, with
both ARM and RV32 using the enlarged 120 KBytes heap.
