matrix.h had unknown function nrows() and ncols() that should not have compiled

matrix.h would not compile on XCode 16.4 and should not have built on other platforms. wxMatrix::ResizePreserve had undefined methods nrows() and ncols() used. Luckily the ResizePreserve function was not used elsewhere in the code base.

@sjanzou Thanks for fixing. I noticed this when trying to build on Mac yesterday. The latest version of XCode is 26. Should we be using Version 16.4 to build SAM?

@cpaulgilman , my Mac has not finished updating to XCode 26, let me test and I will let you know.

Approving for these changes. Happy to re-review for Xcode/Clang version upgrades in the future.
