Units: consistent Meter spelling and abbreviations (#19648)

* fixed unit symbols and description consistency in valueFormats/categories.ts

The preferred English spelling is "litre" (vs "liter") and "metre" (vs "meter"), except in American english. Also, the symbol for Litre is an uppercase 'L', not lowercase.

* Changed metre -> meter in units
