Previously, building LLVM-libc with GWP ASAN was conditioned on the flag
COMPILER_RT_BUILD_GWP_ASAN, which caused issues do to the default value
of the flag being set in the compiler-rt cmake, which is seperate. Now
GWP ASAN is included based on if it exists as a target, which is more
consistent.

malloc, calloc, realloc, and free are all functions that other libc
functions depend on, but are pulled from external sources, instead of
having an internal implementation. This patch adds a way to include
functions like that as entrypoints in the list of external entrypoints,
and includes the malloc functions using this new path.

This patch adds LLVM_LIBC_INCLUDE_SCUDO as a flag. When enabled it
should link in the standalone version of SCUDO as the allocator for LLVM
libc.

This patch provides a way to specify the default target cpu optimizations to use when compiling llvm-libc.
This ensures we don't rely on current compiler's default and allows compiling and cross compiling for a particular target.

Deps are recrusively evaluated at the place they are needed. With this
change, one does not have to list recursive deps of entrypoints when
listing test targets. One will still have to explicitly list all
entrypoint objects when setting up an "add_entrypoint_library" target.

Summary:
The single file was getting too long to be convenient to navigate. This
patch splits it up two into 4 files one each for header rules,
object rules, library rules, and test rules.
