  RuntimeLibcallsEmitter: Add isolated LibcallLibrary variant

This is essentially a hack to not break the common core functions shared
by most targets. Most targets have essentially the same base set of
compiler-rt or libc/libm functions, but a few are so radically different
there is nothing in common (e.g., the GPU targets have a handful of functions,
arm64ec changes every single function). This bit will pull these out of the
library merge-by-name system, and emitted as its own special case. This allows
the single name to be universal across targets without duplicating large
tables in the emitted inc file.
