software: Avoid libase renaming to libutils/libcomm and keep readchar/putsnonl retro-compatibility.
...
We'll maybe do it but that's probably not the right time. We have to make
the picolibc switch as smooth as possible for users (and so avoid update
as much as possible).
In the long term, it would be good to provide a LiteX C SDK, so we'll make
eventual changes when doing this.

cpu/rocket: include core count as per-variant parameter
...
Repurpose (and rename to `CPU_SIZE_PARAMS`) the current
`AXI_DATA_WIDTHS` array. In addition to axi widths for
mem and mmio ports, also include each variant's number
of cores, to facilitate dynamically generated per-core
signals.

Disable LTO for picolibc and use picolibc.specs

Use picolibc.specs to specify integer only printf/scanf.
To do that, we need to pass specs file with options to
the linker. With LTO enabled, name mapping was failing,
so LTO is now disabled for picolibc compilation only.
This also means, that exchange.c and arc4random.c no
longer need to be recompiled and added back.

Libcomm is place for code used for communicating with other

Libutils is code used in multiple places, like crc calculation,
progress bar, memtests.
Libmisc is everything else like sim_debug, which is code for
litex_sim or exception.c for or1k.
