User defined precision and fractional inch are stored on QuantityFormat
construction making changes persistent to object life time.
Change that so until not explicitely overriden, user defined values
are always returned.

Defaults for both precision (number of digits after decimal point)
and denominator (number of fractions) are defined on various places
making difficult to find which default is used for various tasks.
Store these values at one central place: UnitsApi. Unless overriden
by user, default values are defined by unitSchemasDataPack.
Default Unit Schema is not yet changed in onUnitSystemIndexChanged
callback handler, so index needs to be used to request currently
selected one.

Not all unicode characters are allowed as XML output. When writing disallowed characters the SAX parser throws an exception
when loading a project file that results into a broken document and thus to a possible loss of data.
This PR replaces all disallowed characters with an underscore and prints a warning.
This fixes https://github.com/FreeCAD/FreeCAD/issues/22123
Note: It does not fix an already corrupted project file.
This class aims to implement Design Token idea into FreeCAD themes. It
allows themes to use generic variables with generic values so we could
use one qss theme and change the style based on values from preference
packs.
This commit fixes how origin (coordinate system) indicator looks. Before
it showed as disc, and now it shows as point which is more approperiate
given the context.
If the Python profiler is activated then transporting the dict as
exception object is broken where InteractiveInterpreter::runCode()
fails to restore it.
To fix the problem use Exception::setPyException() instead inside
the macto PY_CATCH and the generated wrapper code.
This also improves exception handling in command line mode.
Refactor Units making it constexpr, immutable, with repetition reduced.
Separate data from code.
Constexpr constructed units allow constructing predefined Quantities
from predefined unit types.
Dimensionless quantities have all exponents equal to zero.
Such quantities are simply numbers. The associated unit is
the unit one, symbol 1, although this is rarely explicitly
written.
See chapter 2.3.3 Dimensions of quantities, The International
System of Units, 9th edition.
Quantity is often queried for Unit just to see if it has a dimension.
Ask Quantity directly using isDimensionless() method and modify that
method not to care about Quantity value validity; no user was ever
asking for value validity.
Schema translation previously returned factor 0 and unit string
of input quantity if there was no translation match. Restore
that behaviour as well as returned factor and unit string of
imperial schemas.
