* Fix ChiselStage and Builder handling of logging (#3895)

Previously, object circt.stage.ChiselStage was ignoring the Logger.
Also, Chisel was not creating its own logger scope which could lead to
clobbering of the Console when running invoking Chisel in the same
process multiple times.

Fix various places we had to workaround this behavior and fix tests
checking --log-level debug.

Co-authored-by: Jack Koenig <koenig@sifive.com>

Fix an incorrect assumption in ChiselSim that a 'filelist.f' will exist
that includes all modules, _including blackboxes_, in the design.  Change
this to try to also copy files from the black box filelist.  This makes
ChiselSim work with CIRCT 1.66 and earlier (which put everything in
'filelist.f') and CIRCT 1.66+ (which does not include blackboxes in
'filelist.f').

Note that this is intended as a temporary solution until FIRRTL has a rock
solid ABI that is implemented by CIRCT where all modules can be discovered
under an arbitrary public module.

See CIRCT changes here: https://github.com/llvm/circt/pull/6729

* Fix Reg() to properly handle clocks as rvalues (#3775)

Previously, it was not calling .ref. It was thus not properly:
1. Checking that the clock is bound hardware
2. Checking that the clock is visible in the current scope
3. Reifying the clock if its a view

Note that RegInit() was already correctly calling .ref.

* Add support for configurable warnings (#3414)

Warnings have been assigned unique integers to use as identifiers for
purposes of documentation and configuration.

New CLI option --warn-conf accepts a comma-separated sequence of
<filter>:<action> pairs for customizing warnings.

Supported filters are:
* any          - matches all warnings
* id=<integer> - matches warnings with the integer id
* src=<glob>   - matches warnings where <glob> matches the warning
                 source file

id and src filters can be combined with &.

Supported actions are:
* :s - suppress the warning
* :w - report the warning as a warning (default behavior)
* :e - error on the warning

For example, the new Vec dynamic width matching warning can be
suppressed for source files in src/main/scala while all other warnings
elevated to errors with:
  --warn-conf "id=4&src=src/main/scala/**:s,any:e"

The is also --warn-conf-file which works similarly to --warn-conf except
the <filter>:<action> pairs are newline separated in a file. # is used
for line comments.

This is not a functional bug. The recursive form of reify for Element
would use the .topBinding from the wrong argument, so it would recurse
an extra time, but it would ultimately converge to the right value.
