Add common [container.requirements] type definitions to `CharRange` and `ChunkRange`
The presence of these allow these range classes to be used in various utility functions which require some minimum type of container. For example, this change allows tests to use `EXPECT_THAT(cord.Chunks(), ElementsAre(...))`

Add 'Rebuild' logic to CordRepBtree
There are btree hostile scenarios where an application could perform repeated split/insert/merge operations on a cord leading to a tree exceeding the maximum height. While this should be rare in practice, this change adds a Rebuild() method that will rebuild a tree with a 100% fill factor, and we will invoke this rebuild when a tree exceeds the maximum height. This basically follows the similar 'balance' logic in Concat trees (although the latter is common in Concat uses)

Add 'in place' enabled RemoveSuffix
An in-place RemoveSuffix is more efficient than SubTree() as it can directly modify privately owned nodes and flats allowing easy re-use of free capacity in right-most flats that may turn into Substring edges when using SubTree.

Initial groundwork to allow storing checksum data inside CordRep instances.
This uses a RefcountAndFlags bit that was reserved for this purpose, and will be leveraged in a follow-up change to allow attaching checksums to a Cord's value.
This change splits RefcountAndFlags::IsOne() into two distinct operations:
* IsOne(): This returns true when the associated CordRep is not shared with other threads. This is useful for functions that consume CordRep instances; for example, code that consumes an unshared CordRep can assume ownership of its children without modifying those refcounts.
* IsMutable(): This returns true when the associated CordRep reference is not shared with other threads, *and* does not store an associated checksum value. This is useful for functions that modify a CordRep's contents: code may modify the bytes of a mutable-unshared CordRep without fear of races with other threads, or of invalidating a stored checksum.
The tricky part of this CL is ensuring that the correct choice between IsMutable() and IsOne() was made at each point. An incorrect application of IsOne() could lead to correctness bugs in the future. Code conditioned on IsOne() may delete the CordRep in question, or assume ownership of its children, but must not modify the CordRep's data without explicitly adjusting the CRC.

Enable Cord Btree as the default Cord implementation.
The Cord Btree implementation has been extensively tested by google. This changes makes the Cord Btree implementation the default implementation. This change should have no impact on current use cases and does not effect any public API or behavior.

FunctionRef is cheaper to construct than a std::function, and the argument is only used during the call, so this is safe. This has the added advantage of allowing the caller to provide a non-movable callable, which can't be converted to a std::function.
