mparser: fix precedence of arithmetic operators
The arithmetic operators are now split into two groups:
* The add/sub group: +, -
* The mul/div group: *, /, %
All operators within the same group are left-associative and have equal
precedence. The mul/div group has a higher precedence than the add/sub
group, as one would expect.
Previously every operator had a different precedence and was
right-associative, which resulted in surprising behavior.
This is a potentially breaking change for projects that relied on the
old incorrect behavior.
Fixes #6870
