75635dbf0b [FEATURE][symbology] Add options to dynamically tweak dash pattern 
in simple line symbol layers

New options are:

- Align dash pattern to line length: If checked, the dash pattern lengths
will be subtely adjusted in order to ensure that when a line is rendered
it will end with a complete dash element, instead of a gap element or
partial dash element

- Tweak dash pattern at sharp corners: If checked, this option dynamically
adjusts the dash pattern placement so that sharp corners are represented
by a full dash element coming into and out of the sharp corner. It's designed
to better represent the underlying geometry while rendering dashed lines,
especially for jagged lines

e859a0f846 Fix QgsFieldExpressionWidget generates an invalid expression if a 
field name with a space is selected from the dropdown list and then
the expression editor button is clicked

Previously, the expression editor would open with an unquoted field
name, which was broken for field names containing spaces. Now, we
always ensure that the editor opens with a valid expression

Virtual dataset groups for mesh layer (#37605) 
[FEATURE] Introduces mesh virtual datasets

With the mesh calculator the user can choose to create those "virtual" dataset groups that will be added to the layer. Then, for these dataset groups, values are not stored in memory but each dataset is calculated when needed whit the formula entered in the mesh calculator.

Those virtual dataset groups are saved with the project.

If needed, the user can remove them or can persist them on files to make them persistent.

And fix Python exception handling in QgsField::convertCompatible to
avoid Python "returned an object with the error set" error message

exception message
