This can:
- Make it easier to scroll up and down the commands list
- Avoid pushing up users' previous output
- Allow users to do basic search with `/<word>`

Bundler is special since it's not actually locked in the lockfile as a
regular gem (only via `BUNDLED WITH`). So exclude it from that check.

* Sync YARP gemspec
We were previously not syncing the YARP gemspec over which meant
that the Ruby YARP gem was out of sync.
* Sync YARP node / lex_compat files

IRB already has several features that rely on rdoc, such as:
- Autocompletion's document dialog
- Autocompletion's `PerfectMatchedProc`
- The `show_doc` command
- Easter egg
And we could use its pager more in the future too. So it makes sense to
declare rdoc as a dependency instead of relying on the one bundled with
Ruby.

Remove rb_control_frame_t::__bp__ and optimize bmethod calls
This commit removes the __bp__ field from rb_control_frame_t. It was
introduced to help MJIT, but since MJIT was replaced by RJIT, we can use
vm_base_ptr() to compute it from the SP of the previous control frame
instead. Removing the field avoids needing to set it up when pushing new
frames.
Simply removing __bp__ would cause crashes since RJIT and YJIT used a
slightly different stack layout for bmethod calls than the interpreter.
At the moment of the call, the two layouts looked as follows:
┌────────────┐ ┌────────────┐
│ frame_base │ │ frame_base │
├────────────┤ ├────────────┤
│ ... │ │ ... │
├────────────┤ ├────────────┤
│ args │ │ args │
├────────────┤ └────────────┘<─prev_frame_sp
│ receiver │
prev_frame_sp─>└────────────┘
RJIT & YJIT interpreter
Essentially, vm_base_ptr() needs to compute the address to frame_base
given prev_frame_sp in the diagrams. The presence of the receiver
created an off-by-one situation.
Make the interpreter use the layout the JITs use for iseq-to-iseq
bmethod calls. Doing so removes unnecessary argument shifting and
vm_exec_core() re-entry from the interpreter, yielding a speed
improvement visible through `benchmark/vm_defined_method.yml`:
patched: 7578743.1 i/s
master: 4796596.3 i/s - 1.58x slower
C-to-iseq bmethod calls now store one more VALUE than before, but that
should have negligible impact on overall performance.
Note that re-entering vm_exec_core() used to be necessary for firing
TracePoint events, but that's no longer the case since
9121e57a5f.

* Define RelineInputMethod::HISTORY
The HistorySavingAbility module doesn't do anything if the input method
class doesn't define HISTORY.
- 3ac96be660/lib/irb/history.rb (L10)
- 3ac96be660/lib/irb/history.rb (L34)
This patch defines RelineInputMethod::HISTORY to avoid this.
* Improve history-saving's ability check
Instead of checking the existence of `input_method_class::HISTORY`, we should
make every input method class declare if it supports history saving or not.
Since the default value is `false`, it shouldn't break any custom input method
that inherits from `IRB::InputMethod`.

Previously, when sorting and comparing git Gemfile vs lockfile sources during
`bundler/setup` to figure out whether we need to re-resolve or not, we
would try to find the default branch if nothing more specific was
specified in the Gemfile.
If the git cache has been deleted thought, that would fail.
The error would still be swallowed (and the branch would simply not be
displayed), but trying to clone would still generate the side effect of
creating the parent folder for the clone.
That could affect non-writable systems that don't expect `bundler/setup`
to write to the filesystem at all.
To fix this, override `Bundler::Source::Git#identifier` to use
exclusively static information, so it does not even try to clone the
repo nor generate any side effects.
