[libc][mem*] Introduce Sized/Backends for new mem framework
This patch is a subpart of D125768 intented to make the review easier.
The `SizedOp` struct represents operations to be performed on a certain number of bytes.
It is responsible for breaking them down into platform types and forwarded to the `Backend`.
The `Backend` struct represents a lower level abstraction that works only on types (`uint8_t`, `__m128i`, ...).
It is similar to instruction selection.

[libc] Implement FLAGS option for generating all combinations for targets.
Add FLAGS option for add_header_library, add_object_library,
add_entrypoint_object, and add_libc_unittest.
In general, a flag is a string provided for supported functions under the
multi-valued option `FLAGS`. It should be one of the following forms:
FLAG_NAME
FLAG_NAME__NO
FLAG_NAME__ONLY
A target will inherit all the flags of its upstream dependency.
When we create a target `TARGET_NAME` with a flag using (add_header_library,
add_object_library, ...), its behavior will depend on the flag form as follow:
- FLAG_NAME: The following 2 targets will be generated:
`TARGET_NAME` that has `FLAG_NAME` in its `FLAGS` property.
`TARGET_NAME.__NO_FLAG_NAME` that depends on `DEP.__NO_FLAG_NAME` if
`TARGET_NAME` depends on `DEP` and `DEP` has `FLAG_NAME` in its `FLAGS`
property.
- FLAG_NAME__ONLY: Only generate 1 target `TARGET_NAME` that has `FLAG_NAME`
in its `FLAGS` property.
- FLAG_NAME__NO: Only generate 1 target `TARGET_NAME.__NO_FLAG_NAME` that
depends on `DEP.__NO_FLAG_NAME` if `DEP` is in its DEPENDS list and `DEP`
has `FLAG_NAME` in its `FLAGS` property.
To show all the targets generated, pass SHOW_INTERMEDIATE_OBJECTS=ON to cmake.
To show all the targets' dependency and flags, pass
`SHOW_INTERMEDIATE_OBJECTS=DEPS` to cmake.
To completely disable a flag FLAG_NAME expansion, set the variable
`SKIP_FLAG_EXPANSION_FLAG_NAME=TRUE`.

[libc] Adding memcpy implementation for x86_64
Summary:
The patch is not ready yet and is here to discuss a few options:
- How do we customize the implementation? (i.e. how to define `kRepMovsBSize`),
- How do we specify custom compilation flags? (We'd need `-fno-builtin-memcpy` to be passed in),
- How do we build? We may want to test in debug but build the libc with `-march=native` for instance,
- Clang has a brand new builtin `__builtin_memcpy_inline` which makes the implementation easy and efficient, but:
- If we compile with `gcc` or `msvc` we can't use it, resorting on less efficient code generation,
- With gcc we can use `__builtin_memcpy` but then we'd need a postprocess step to check that the final assembly do not contain call to `memcpy` (unlikely but allowed),
- For msvc we'd need to resort on the compiler optimization passes.
