TLSF memory allocator. Less free flash, moar free ram. (#3572)

* add tlsf as submodule
* libs: tlsf
* Furi: tlsf as allocator
* Furi: heap walker
* shmal fixshesh
* f18: tlsf
* PVS: ignore tlsf
* I like to moving
* merge upcoming changes
* memmgr: alloc aligned, realloc
* Furi: distinct name for auxiliary memory pool
* Furi: put idle and timer thread to mem2
* Furi: fix smal things in allocator
* Furi: remove aligned_free. Use free instead.
* aligned_malloc -> aligned_alloc
* aligned_alloc, parameters order
* aligned_alloc: check that alignment is correct
* unit test: malloc
* unit tests: realloc and test with memory fragmentation
* unit tests: aligned_alloc
* update api
* updater: properly read large update file
