  [APFloat] Inline static getters (#163794)

This patch exposes the declaration of fltSemantics to inline
PPCDoubleDouble() calls in the IEEEFloat/DoubleAPFloat dispatch.
It slightly improves the compile time:

With https://github.com/llvm/llvm-project/pull/111544, the improvement
is more significant:

Address comment

If breaking changes are allowed, we can encode all the properties of
fltSemantics within a 64-bit integer. Then we don't need `Semantics <->
const fltSemantic` conversion.
