Setting `\hfuzz=\maxdimen` completely breaks X columns

[IsaacOscar]

In order to silence annoying overfull hbox warnings when I'm compiling a draft, I set \hfuzz=\maxdimen. But this broke all my X columns (they were 0 width). I found the cause of the problem:

Using xpatchcmd I modifed the above to use 0pt in place of \hfuzz, which solved my problem.

But not having to use xpatchcmd would probably be better, I'd submit a pull request myself, but I'm not sure what that line is actually doing, and whether 0pt is a sensible value, or even if it would be usefull to make it user configurable.

We need to use our own hfuzz dimension instead of global \hfuzz dimension in tabularray.

PS: I just followed the usage of tabu packgae when I was writing this part of code.

This bug has been fixed.
