  [WGSL] Constant bitcast function does not handle vectors of doubles

Reviewed by Mike Wyrzykowski.

Bitcast needs to accept abstract values due to special edge cases, but it also
needs to concretize the values for the default case. We were missing a conversion
from double (abstract float) to f32 when bitcasting between vectors of different
sizes.
