Rename ftrace_regs_return_value to ftrace_regs_get_return_value as same as
other ftrace_regs_get/set_* APIs. arm64 and riscv are already using this
new name.

Since the arch_ftrace_get_regs(fregs) is only valid when the
FL_SAVE_REGS is set, we need to use `&arch_ftrace_regs()->regs` for
ftrace_regs_*() APIs because those APIs are for ftrace_regs, not
complete pt_regs.

Most architectures use pt_regs within ftrace_regs making a lot of the
accessor functions just calls to the pt_regs internally. Instead of
duplication this effort, use a HAVE_ARCH_FTRACE_REGS for architectures
that have their own ftrace_regs that is not based on pt_regs and will
define all the accessor functions, and for the architectures that just use
pt_regs, it will leave it undefined, and the default accessor functions
will be used.
Note, this will also make it easier to add new accessor functions to
ftrace_regs as it will mean having to touch less architectures.
