  [AArch64][GlobalISel] Fix lowering of i64->f32 itofp. (#132703)

This is a GISel equivalent of #130665, preventing a double-rounding
issue in sitofp/uitofp by scalarizing i64->f32 converts. Most of the
changes are made in the ActionDefinitionsBuilder for G_SITOFP/G_UITOFP.
Because it is legal to convert i64->f16 itofp without double-rounding,
but not a fpround f64->f16, that variant is lowered to build the two
extends.
