Kernel/SDK: implement `store_read_all` and `store_write_all`

Context

The current version of store_read (and store_write) currently cannot read (write) more than 2048 at once, following the host functions implementation. This MR implements store_read_all and store_overwrite_all that can read and write arbitrary big values.

Note that these two functions have been implemented in !8147 (closed), but it might be useful to generalize them.

It depends on !8567 (merged).

Manually testing the MR

Run the tests, as no kernel uses it for now:

make build-kernels
