Fix sign of shift operators
...
This one:
map->mask = (1 << (next_bit + bits_needed)) - (1 << next_bit);
before the fix, the shift was done as an int, causing overflow
if it ever got to 1 << 31. Sprinkle 'u's around.

Remove unused HB_SHAPER_DATA_ENSURE_DECLARE lines.
...
The coretext_aat shaper delegates to the regular coretext_..._ensure() functions, so coretext_aat_..._ensure() functions defined by these macros are unused. The compiler warns about them, which in turn can confuse people to think that the coretext_aat_..._ensure() functions weren't called by accident.
