feat: implement material3 table foundation in pkg/x/m3table

[zodimo]

Added the new component pkg/x/m3table/table.go and pkg/x/m3table/options.go containing Table(), Column, and TableOptions. Includes logic to generate headers dynamically and apply specific layout modifiers (weight, size.Width) to wrap and layout cells correctly in a column-row grid format.

What about row height constraints ?

What about row height constraints ?

I've added minimum row height constraints. They are configurable via TableOptions using WithMinHeaderRowHeight and WithMinRowHeight, defaulting to Material 3 standard sizes (56dp and 52dp respectively).
