  [flang][runtime] Support SPACING for REAL(2 & 3) (#106575)

Add runtime APIs for the intrinsic function SPACING for REAL kinds 2 & 3
in two ways: Spacing2 (& 3) for build environments with std::float16_t,
and Spacing2By4 (& 3By4) variants (for any build environment) which
compute SPACING for those types but accept and return their values as
32-bit floats.

SPACING for REAL(2) is needed by HDF5.
