Fix te_expr's flexible array member
...
te_expr has a flexible array member, but it's declared as size 1.
Stop declaring its size so UBSan stops complaining.
Noted in #2852

tinyexpr: Prevent possible division by zero
...
This is possibly not actually undefined behavior because IEEE754
defines _more_ of division-by-zero, but let's be careful.
Fixes #2852 .

Revert "tinyexpr: Make te_expr a class"
...
Turns out this crashes on musl when doing te_expr::parameter.push_back(). For some reason.
This reverts commit 2e11e6c692

tinyexpr: Reserve arity parameters

This somehow fixes heap-buffer-overflow? I thought this was supposed
to be safe.

tinyexpr: Move enums together and stop explicit numbering
...
We should _not_ be doing bit-fiddling with these, so there's no reason
to care about the number.
This also removes the unused "TE_VARIABLE" symbol.

tinyexpr: Free all parameters again
...
This used implicit fallthrough to free all.
We still iterate back-to-front (i--) because maybe that's important?

tinyexpr: Unfiddle the bits
...
Mainly this removes the "TYPE_MASK" macro that just masks off the
higher bits, which I don't think were ever actually used.
Much of this seems like anticipation of future direction, but we're
going somewhere else.

tinyexpr: Remove PURE flag
...
This was unused because all functions were marked as pure. We don't
have any plans to add any that aren't, and if we did we'd still have
this in git.

[tinyexpr] Port to C++
...
This removes the need to run c-compilation on one file, and allows us
to in future c++-ify this a bit.
There's a lot of bit-fiddling here that is quite unnecessary, better
error-handling would be nice...
So far this removes a few more unused things (because I would have had
to port them), including:
- Functions with ARITY > 3 (even 3 isn't used, but just so we don't
get complacent)
- Variables
- Most functions moved out of the header, because only te_interp is used.
- The te_print function
