Move stuff out of libbase
...
Removed libbase completely and moved remaining files into
libutils, libcomm and libmisc.
Libcomm is place for code used for communicating with other
devices, which doesn't yet live in its own liblite*.
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.

Enable LTO
...
Use gcc-ar and gcc-nm, because they have LTO plugins
Turn off LTO for libcompiler_rt, exchange.c and arc4random.c
from newlib.
Also add getentropy, dummy function, because for some reason
libbase/console.c wants it.

Implement initial support for lm32 and or1k
...
Picolibc doesn't maintain meson.build or cross*.txt files
for lm32 and or1k CPUs.
This commit adds meson.build files for both of them.
Also libc/Makefile got modifed to determine CPU family
from $(CPU) value and generate cross.txt file.
Now picolibc gets compiled with LiteX flags too.
It doesn't compile on neither of them yet,
but at least riscv still works.

Remove libbase-nofloat.a variant
...
As vsnprintf is no longer compiled it was
identical to libbase.a.
Picolibc defines levels of printf and scanf
https://github.com/picolibc/picolibc/blob/main/doc/printf.md#printf-and-scanf-levels-in-picolibc
so those should probably be used.

Replace putsnonl(s) with fputs(s, stdout)

It won't compile, because stdout is undefined, but

Create __iob for picolibc
...
Picolibc requires __iob array for its IO functions
This commit creates such array with dummy functions
using putchar/readchar from console.c
To prevent name conflicts printf and others were
removed from console.c
Also putchar had to be renamed to base_putchar

liblitespi/spiflash: Move memspeed to specific function (spiflash_memspeed) and reduce test size.
...
On slow configurations (ex iCEBreaker / SERV CPU / 12MHz SPI Flash freq) memspeed test was
too slow (>200s to do the random test for 1MB), so reduce test size to 4KB.
This will be less accurate but will still provide representative results which
is the aim of this test.

litespi/integration: Review/Cleanup #1024 .
...
Integration from #1024 was working on some boards (ex Arty) but breaking others (ex iCEBreaker);
simplify things for now:
- Avoid duplication in spiflash_freq_init.
- Avoid passing useless SPIFLASH_LEGACY flag to software (software can detect it from csr.h).
- Only keep integration support for "legacy" PHY, others are not generic enough and can be passed with phy parameter.
