Completion context (#4017)
* completion-context: Add CompletionContextParser placeholder

Implements the xonsh (tab-)completion context parser.
This parser is meant to parse a (possibly incomplete) command line.

* completers: tools: Implement ``contextual_completer`` decorator

This is used to mark completers that want to use the parsed completion context.

* completers: Enable using contextual completers in xonsh/completer.py

* completers: readline, ptk, jupyter: Enable using contextual completers

Pass ``multiline_text`` and ``cursor_index`` to ``Completer.complete()``

* parsers: base: Refactor out a ``raise_parse_error`` function

* tokenize: Enable ``tolerant`` mode

If ``tolerant`` is True, yield ERRORTOKEN instead of
    throwing an exception when encountering an error.

* lexer: Enable ``tolerant`` mode

Tokenize without extra checks (e.g. paren matching).
When True, ERRORTOKEN contains the erroneous string instead of an error msg.

* tests: lexer: Test ``tolerant`` mode

* completion-context: Implement simple CommandContext parsing

* completion-context: tests: Test simple CommandContext parsing

* completion-context: Implement parsing sub-commands

* completion-context: tests: Test parsing sub-commands

* completion-context: Add news file

* completion-context: parser: Add parser table path to relevant locations

Code-coverage, mypy ignore list, etc.

* completion-context: Implement parsing partial strings and line continuations

* completion-context: tests: Test parsing partial strings and line continuations

* completion-context: Convert ``Span`` object to a ``slice``

* completion-context: Refactor out ``create_command`` and ``cursor_in_span``

* completion-context: Implement handling empty commands

* completion-context: tests: Test handling empty commands

* completion-context: Implement handling multiple commands

Separated by newlines, `;`, `and`, `or`, `|`, `&&`, `||`

* completion-context: tests: Test handling multiple commands

Separated by newlines, `;`, `and`, `or`, `|`, `&&`, `||`

* completion-context: Implement handling python context

* completion-context: tests: Test handling python context

* completers: tools: Add `contextual_command_completer`

* completers: Make `complete_skipper` contextual

* completers: Make `complete_from_man` contextual

* completers: Make `complete_from_bash` contextual and add test

* completers: Make `complete_pip` contextual and update tests

* completers: Keep opening string quote if it exists

* completion-context: Handle cursor after a closing quote

For example - cursor at the end of ``ls "/usr/"``.
1. The closing quote will be appended to all completions.
 I.e the completion ``/usr/bin`` will turn into ``/usr/bin"``
2. If not specified, lprefix will cover the closing prefix.
 I.e for ``ls "/usr/"``, the default lprefix will be 6 to include the closing quote.

* completion-context: tests: Test handling cursor after a closing quote

* completion-context: Fix bug with multiple empty commands

e.g. `;;;`

* completion-context: tests: Speed up tests

From ~15 seconds to ~500 ms

* completion-context: Expand commands and subcommands

* completion-context: Simplify `commands` rules

* completion-context: Simplify `sub_expression` rules

* completion-context: Simplify editing a multi-command token

* completion-context: Inline `create_command`

* completion-context: Implement `contextual_command_completer_for` helper

* completers: Make `complete_cd`/`complete_rmdir` contextual and add tests

* completers: path: Don't append a double-backslash in a raw string

When completing a path, if a raw string is used (e.g. `r"C:\Windows\"`),
there's no reason to append a double-backslash (e.g. `r"C:\Windows\\"`).

* completers: Make `complete_xonfig`/`complete_xontrib` contextual and add tests

* completers: Make `complete_completer` contextual and add tests

* completers: Make `complete_import` contextual and add tests

* completion-context: Add python `ctx` attribute

* completion: tools: Simplify `RichCompletion` attributes handling

* completers: Make `base`, `python`, and `commands` contextual

* Add tests
* No need for `python_mode` completer anymore

* completion: tools: Add `append_space` attribute to `RichCompletion`

* completion-context: Get all lines in a main python context

* xontrib: jedi: Make the `jedi` completer contextual

* completers: tools: Remove `get_ptk_completer` and `PromptToolkitCompleter.current_document`

These aren't needed anymore now that contextual completers can access the multiline code (via `PythonContext.multiline_code`).

* completion-context: ptk: Expand aliases

* completion-context: jupyter: Expand aliases and fix line handling

* completer: Preserve custom prefix after closing quote

* completers: bash: Ensure bash completion uses the complete prefix

* completers: pip: Append a space after a pip command

* completers: pip: Prevent bad package name completions

* completers: Remove a common prefix from `RichCompletion` if `display` wasn't provided

* completion-context: Treat cursor at edge of `&& || | ;` as normal args

This will be used for completing a space

* completers: Complete end proc keywords correctly
