feat: add chain debug command (ignite#3221)

* feat: add support to compile chain app without optimizations

* feat: add `debugger` package

* chore: change `cliui` package to allow multiple `Session.End()` calls

* feat: add `chain debug` command to launch a debugging session

* feat: add debug server support to `chain debug` command

This allows running a debug server without launching a debug client
which is useful to debug using other clients like gdlv or VSCode.

* chore: consistency changes

* chore: add missing handling for config flag

* chore: fix GRPC address

* feat: add bubbletea UI to `chain debug` when `--server` flag is present

* chore: remove some `chain debug` flags in favour of default values

* refactor: simplify debug command by removing build functionality

To keep the command simple it only starts the debug shell or server
favouring the build and init commands to init/reset blockchain app data
or to build the debug binary.

Both build and init commands have now a `--debug` flag to build a binary
for debugging.

* chore: change `ignite serve` to build a debugging binary

* docs: add long description for `ignite debug` command

* test: add unit tests for `chain debug` server UI views

* fix: change error output to be consisten between UI & non UI runs

Bubbletea UI is used when the debug server is run (--server flag) while
a standard Cobra command is used when running the debug console. The
debug command without `--server` runs outside Bubbletea because the
debugger needs control over stdout.

* refactor: use a single `AddCommand` call to register commands

* chore: remove redundant `AddCommand` calls

* chore: change chain debug command variable name to match flag name

* chore: move disconnect channel init to debug options initialization

* docs: add docstrings to public model methods
