Set a single param toggle to the work-around used to deal with faulty resets on ARM

Due to #1674, optionsx.h has a series of IF_X86_ELSE work-arounds in order to turn off reset parameters on ARM. Having so many IF_X86_ELSE is not necessary, as all these parameters should be toggled via the main reset param, namely -enable_reset. This issue covers the removal of these IF_X86_ELSE.

An example of such an unneeded IF_X86_ELSE is shown below:

 OPTION_DEFAULT(uint, reset_at_vmm_percent_free_limit,
        IF_X86_ELSE(10, 0), /* i#1674: re-enable on ARM once xl8 bugs are fixed */
