[libc] Basic implementation of crt0 (#146863)
In order to run hermetic tests downstream (#145349), we need startup
code. This is based on the crt0 that is present in Arm Toolchain:
https://github.com/arm/arm-toolchain/tree/5446a3cbf4ef73196ccce490fc9fbf87bee093aa/arm-software/embedded/llvmlibc-support/crt0.
Note that some tests do fail due to lack of hardware setup, which will
be implemented at a later time.
Most of the CMake/structure is a copy from the existing code in both
`libc/startup/linux` and `libc/startup/gpu`. It is required to build an
object file to be linked with.
Also add header files for init/fini such that crt0 can use the provided
symbols.
