x86/fpu: Configure init_fpstate attributes orderly
The init_fpstate setup code is spread out and out of order. The init image
is recorded before its scoped features and the buffer size are determined.
Determine the scope of init_fpstate components and its size before
recording the init state. Also move the relevant code together.
