Math commands can work with bounded ranges and produce list of numbers (#15319)

No associated issue, but follows up #15135. See also discussion on

# Description

### Math commands `range -> list<number>`

This enables the following math commands:
- abs
- ceil
- floor
- log
- round

to work with ranges. When a range is given, the command will apply the
command on each item of the range, thus producing a list of number as
output.

Example

The commands still do not work work with unbounded ranges:

And I left out the "mode" command because I think it does not make sense
to use it on ranges...

### Math commands `range -> number`

This was the topic of my previous PR, but for whatever reason I didn't
do `math variance` and `math stddev`.
I had to use `input.try_expand_range` to convert the range into a list
before computing the variance/stddev.

And same, does not work in infinite ranges:

# User-Facing Changes
- Command signatures changes
- ability to use some commands with unbounded ranges
- ability to use variance and stddev with bounded ranges

# Tests + Formatting
Cargo fmt and clippy OK
Tests OK
