Path Enhancement Project #2: parse, join and split (#3256)
* Add new path parse subcommand

This includes a slight refactor to all the path subcommand `action()`
functions.

* Remove filestem and extension; Fix example

* Add additional description to path parse

* Put join arg behind flag; Fix missing import (Win)

* Fix error when column path is passed as arg

* Add structured path joining

Structured path is implicitly joined at every patch subcommand call.

* Fix existing path join tests; Fix rustfmt

* Remove redundant 'static lifetime (clippy)

* Add initial impl of path split subcommand

* Add ability to join path from parts

* Fix wrong results in path split examples

* Fix remaining asyncs after engine change

* Do not wrap split path parts into table

When the input is just a list of values, the `path split` command will
split each value directly into the output stream, similar to
`split-row`. Column path--specified values are still wrapped into a
table so they can still be used to replace table fields.

* Join list of values instead of going one-by-one

When `path join` encounters a list of values, it attempts to join them,
instead of going one-by-one like the rest of the path commands. You can
still `each { echo $it | path join }` to join them one-by-one, if the
values are, e.g., tables.

Now, the behavior of `path split` and `path join` should match the
`split-row` and `str collect` counterparts and should hopefully align
better with user's expectations.

* Make sure path join detects structured path

* Fix panic on empty input stream

Also, doesn't collect input into vector unnecessarily.

* Fix path join not appending value

* Remove argument serialization

* Make better errors; Misc refactor

* OsStr -> String encoding is now lossy, instead of throwing an error
* The consequence is action() now always returns Value instead of Result
* Removed redundant handle_value() call in `path join`
* Fix possible incorrect error detection in `path split`
* Applied rustfmt + clippy

* Add more usage, examples & test; Fix type error

The 'parent' column was required to be a path but didn't work with
string.

* Add more help & examples; Maybe fix Windows error

* Refactor operate function

Reducing code repetition

* Review usages and examples

* Add the option to manually specify the extension

* Add more tests; Fix failures on Windows

* Move path commands to engine-p

* Small refactor
