Catherine bf5a960668 fmt,cxxrtl: add `UNICHAR` format type. 
This format type is used to print an Unicode character (code point) as
its UTF-8 serialization. To this end, two UTF-8 decoders (one for fmt,
one for cxxrtl) are added for rendering. When converted to a Verilog
format specifier, `UNICHAR` degrades to `%c` with the low 7 bits of
the code point, which has equivalent behavior for inputs not exceeding
ASCII. (SystemVerilog leaves source and display encodings completely
undefined.)

Catherine 1780e2eb1e fmt,cxxrtl: add support for `NUMERIC` justification. 
Before this commit, the existing alignments were `LEFT` and `RIGHT`,
which added the `padding` character to the right and left just before
finishing formatting. However, if `padding == '0'` and the alignment is
to the right, then the padding character (digit zero) was added after
the sign, if one is present.

After this commit, the special case for `padding == '0'` is removed,
and the new justification `NUMERIC` adds the padding character like
the justification `RIGHT`, except after the sign, if one is present.
(Space, for the `SPACE_MINUS` sign mode, counts as the sign.)

Catherine 6d6b138607 fmt,cxxrtl: support `{,PLUS_,SPACE_}MINUS` integer formats. 
The first two were already supported with the `plus` boolean flag.
The third one is a new specifier, which is allocated the ` ` character.
In addition, `MINUS` is now allocated the `-` character, but old format
where there is no `+`, `-`, or `-` in the respective position is also
accepted for compatibility.

Catherine a5441bc00c fmt: `FmtPart::{STRING→LITERAL},{CHARACTER→STRING}`. 
Before this commit, the `STRING` variant inserted a literal string;
the `CHARACTER` variant inserted a string. This commit renames them
to `LITERAL` and `STRING` respectively.

Catherine b74d33d1b8 fmt: rename TIME to VLOG_TIME. 
The behavior of these format specifiers is highly specific to Verilog
(`$time` and `$realtime` are only defined relative to `$timescale`)
and may not fit other languages well, if at all. If they choose to use
it, it is now clear what they are opting into.

This commit also simplifies the CXXRTL code generation for these format
specifiers.

Catherine a33acb7cd9 cxxrtl: refactor the formatter and use a closure. 
This commit achieves three roughly equally important goals:
1. To bring the rendering code in kernel/fmt.cc and in cxxrtl.h as close
   together as possible, with an ideal of only having the bigint library
   as the difference between the render functions.
2. To make the treatment of `$time` and `$realtime` in CXXRTL closer to
   the Verilog semantics, at least in the formatting code.
3. To change the code generator so that all of the `$print`-to-`string`
   conversion code is contained inside of a closure.

There are two reasons to aim for goal (3):
a. Because output redirection through definition of a global ostream
   object is neither convenient nor useful for environments where
   the output is consumed by other code rather than being printed on
   a terminal.
b. Because it may be desirable to, in some cases, ignore the `$print`
   cells that are present in the netlist based on a runtime decision.
   This is doubly true for an upcoming `$check` cell implementing
   assertions, since failing a `$check` would by default cause a crash.

Martin Povišer 189064b8da rtlil, hashlib: Remove deprecated `std::iterator` usage 
`std::iterator` has been deprecated in C++17. Yosys is being compiled
against the C++11 standard but plugins can opt to compile against a
newer one. To silence some deprecation warnings when those plugins are
being compiled, replace the `std::iterator` inheritance with the
equivalent type declarations.
