BTF: Support for BTF_KIND_FLOAT
Add BTF_KIND_FLOAT, a new BTF type kind which has recently stabilized in
the linux kernel [1]. This kind is used for encoding floating point
types, and is of particular use when generating BTF for some s390
arch-specific kernel headers.
Also update some BTF tests which previously used floating point types to
check correct behavior for types with no BTF representation.
