dd41e147f8 feat(Expression): Add color_mix function 
It takes string representation or color object as arguments so the
function can work with CMYK color without changing its color type and converting it to RGB.

b4b84813d3 Be clear that the expressions return invalid when they cannot convert 
I got mislead by the "Nothing is returned if a value cannot be converted" as it led
me to believe I was expecting NULL.

d0c7c6e930 fix formula for exponential interpolation 
The scale_exp function renamed to scale_polynomial and has an alias
scale_exp to preserve backward compatibility.

A new function using correct formula was added as scale_exponential.

49adde6b9a [expressions] Re-permit format_number to omit group separators 
After 6fcef30cc50, group separators were always included in the
results from format_number (even if a locale which doesn't use
them like the 'C' locale is specified). 6fcef30cc50 was added
to fix an old regression, but in doing so we lost flexibility
to skip unwanted separators.

Workaround this by introducing a new opt-in omit_group_separators
argument for format_number to skip the thousand separators when
desired. Also add an opt-in trim_trailing_zeroes argument for
further flexibility.

390cb760c9 [feature][expressions] Add feature_id(some feature) function 
Allows for retrieving the feature ID of a feature object. Accepts
one argument which must be a feature object. Accordingly this
function can be used with the results of any other function
which returns feature objects, such as "get_feature", "overlay_*",
etc.

b23eb1d250 [feature] New function "load_layer" 
This function (available only in Processing expressions for now),
allows loading a map layer via a source string and provider name.

It is designed to allow use of the expression functions which
directly reference map layers (such as the aggregate functions)
with a hardcoded layer path, eg. then permitting these functions
to be used outside of a project (such as via the qgis_process tool)
