Format testsuite scripts, pol-core support modules (#713)
* Format escript testsuite

* Manual formatting for escript testsuite
- Add format-off to places where formatter does what it should, but we don't like the results
- Manually change places where formatter outputs weird things _without_ format-off, so next format-all would show changes if not fixed

* Update .err files; add update_err.py helper script

Use the format `:line:col: message` for all .err file checks. This
allows us to change the file names without needing to edit the .err
contents.

Note that `in/inc0{1,2}.err` need have error messages between POSIX and
Windows, so their messages are a bit more "generic" than the other errs.

* Format pol testsuite

* Manual formatting for pol testsuite

* Format pol-core modules

* Manual formatting for pol-core modules

* Additional format pol-core modules

Use FormatterLineWidth=10000 since module functions must be on one line
because of the parse_modules target

* Address Discord comments

- Support multi-line module function declarations in parse_modules

* Format on df07831

// Radian <-> Degrees Conversion
RadToDeg( radians );
DegToRad( degrees );
Min( x, y := 0 ); // returns minumum of x and y or lowest Element in given array
Max( x, y := 0 ); // returns maximum of x and y or biggest Element in given array
Pow( x, y ); // returns x ^ y
Sqrt( x ); // returns square root of x
Root( x, y ); // returns y root of x (same as Pow(x,1.0/y))
Abs( x ); // returns absolute value (works on Reals and Integers)
Log10( x ); // Returns log(base 10) of x
LogE( x ); // Returns natural log of x
// rounding functions
Ceil( x ); // returns Real that is smallest integer >= x
Floor( x ); // returns Real that is largest integer <= x
// functions to return some constants
