Placeholders that GCodeProcessor fills in after the G-code is generated
(print_time_total_sec and the other print_time_* parts,
used_filament_length, and the print statistics such as total_weight)
hold a tag such as @TOTAL_WEIGHT@ while the template is evaluated.
Multiplying one already failed with a type error. Adding a number
joined the tag as text, so {total_weight + 5} printed 123.455 for a
123.45 g print, and a comparison compared the tag as text, so
{if total_weight > 100} was always true. Neither gave an error.
PlaceholderParser::set_deferred() now registers such a value. Printing
it and joining it to text work as before. A calculation, a comparison,
a regex or a condition on it fails with an error that says the value is
known only after the G-code is generated, also after it was copied to a
variable or through regex_replace(). Adding a number or another
deferred value to one is treated as a sum and fails too. Text that
already contains one joins a number as text, like any other string.
filament_change() inside an {if} branch that is not taken now does
nothing. It used to set the current extruder from an uninitialized
value.
