[lldb][TypeSystem] Remove count parameter from TypeSystem::IsFloatingPointType (#165707)

Similar motivation to https://github.com/llvm/llvm-project/pull/165702.
It was unused in all callsites and inconsistent with other APIs like
`IsIntegerType` (which doesn't take a `count` parameter).

If we ever need a "how many elements does this type represent", we can
implement one with a new TypeSystem API that does exactly that.

Some callsites checked for `count == 1` previously, but I suspect what
they intended to do is check for whether it's a vector type or complex
type, before reading the FP register. I'm somewhat confident that's the
case because the `TypeSystemClang::GetTypeInfo` currently incorrectly
sets the integer and floating point bits for complex and vector types
(will fix separately). But some architectures might choose to pass
single-element vectors in scalar registers. I should probably changes
these to check the vector element size.

All the `count == 2 && is_complex` were redundant because `count == 2`
iff `is_complex == true`. So I just removed the count check there.
