Experimental heap and global allocator which can be optionaly enabled with "heap" feature.

I did some tests with the Rust boilerplate (see LedgerHQ/app-boilerplate-rust#58) and with HEAP_SIZE=8K Ragger tests are ok with S+, X, Stax and Flex. However, for Nano S, it does not even compile, the relocation script fails (5000 bytes overflow). I have tried naively to decrease the heap size down to 2048 bytes, compilation is ok for Nano S but I have core dumped during Ragger tests. With 1024 bytes it works, but not sure it will be enough for any other app (Obsidian, Radix for instance)...
