Update stdio code in libc

Picolibc now requires to create stdin, stdout and stderr files
ourselves instead of __iob array. Thus changes and renaming
of iob.c to stdio.c

Disable thread local storage (TLS) in picolibc
...
It was causing some compilation issues with lm32.
As global errno was enabled anyway, it was easier
to disable TLS whatsoever.

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.

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.

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.

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.

Create __iob for picolibc

Also putchar had to be renamed to base_putchar
