x86/idle: Remove CONFIG_AS_TPAUSE

There is not much point in CONFIG_AS_TPAUSE at all when the emitted
assembly is always the same - it only obfuscates the __tpause() code
in essence.

Remove the TPAUSE insn mnemonic from __tpause() and leave only
the equivalent byte-wise definition. This can then be changed
back to insn mnemonic once binutils 2.31.1 is the minimum version
to build the kernel. (Right now it's 2.25.)
