Suppress some LeakSanitizer errors in unit tests
...
The fontconfig library has some (intentional) memory leaks which
must be suppressed for unit tests with the LeakSanitizer.
This fixes the issues #3156 and #3157 .

"kur" no longer exists, might be named "kur_ara" (the old "kur_ara" is
now "kmr", which is actually Latin) now, but "kur" is not present in
tessdata_fast nor in tessdata_best. [1] [2]
"tgl" (Tagalo) is now named "fil" (Filipino) [3]

We also move to relying on both scales and output having been
padded to accomodate us writing more results than are actually
needed here. This was allowed for a few commits back.

Rejig intsimdmatrix to reduce FP ops.
...
Avoid 1) floating point division by 127, 2) conversion of
bias to double, 3) FP addition, in favour of 1) integer
multiplication by 127, and 2) integer addition.
(Also costs extra work in the serialisation/deserialisation of
the scale values, and conversion of weights to int formats, but
these are all one offs).

Round output buffers for intSimdMatrix.
...
In order to allow intSimdMatrix implementations to 'overwrite'
their outputs, ensure that the output buffers are always padded
to the next block size.
This doesn't make any difference yet, but it enables optimisations
further down the line, especially when the biasing is pulled into
the SIMD.

Tweak scales array for intSimdMatrix case.
...
Currently, the size of the scales array is not rounded up
in the same way as the weights are. This blocks us pushing
the scale calculations into the SIMD, as when we "overread"
the end of the scale array, we potentially get errors.
Here, we adjust the intSimdMatrix stuff to ensure that the
scales array reserves enough entries to allow such overreads
to work.
This doesn't make any difference for now, but opens the way
for future optimisations.
