[reland] Don't redefine macros from base/compiler_specific.h.

Browse Source 
`DISABLE_CFI_ICALL` is already defined in that header; use it.

This is both simpler and less likely to trigger macro redefinition
errors.

This was previously landed in crrev.com/c/5805458, but reverted due to
crbug.com/362787700.
