Description

Based on information from Cygwin toolchain port capable of building functional "Hello World!" executable #183 ticket and in accordance with Reproduce the AArch64 Cygwin toolchain build from #125 #222 ticket port the following Standard C library functions to AArch64:

Notes

For the upstreaming of the whole project, it must be discussed with Cygwin maintainers which implementations should be shared with x64 codebase (implemented in C) and which should be implemented in AArch64 assembly. Hovever for this initial task, it is enough to use C implementations.
Implementation of the functions can be copied or inspired from corresponding implementations in GCC or MinGW codebases.

Acceptance Criteria

The Standard C library functions listed above are ported to AArch64 and they are functional according to the Standard C library specification or their corresponding x64 Cygwin imlementation (whatever is appliable, discuss with Cygwin maintainers if in doubts).
The Cygwin AArch64 build addressed in Reproduce the AArch64 Cygwin toolchain build from #125 #222 ticket do not fail on the implemented functions.
