HASUMI Hitoshi 03a426ec8d [Feature #22279] Add region arguments to String bit operations (#18562) 
This patch extends the following String methods:

* String#bit_set(offset, length, lsb_first: true) -> self
* String#bit_set(range, lsb_first: true) -> self
* String#bit_clear(offset, length, lsb_first: true) -> self
* String#bit_clear(range, lsb_first: true) -> self
* String#bit_flip(offset, length, lsb_first: true) -> self
* String#bit_flip(range, lsb_first: true) -> self
* String#bit_count(offset, length, lsb_first: true) -> Integer
* String#bit_count(range, lsb_first: true) -> Integer

HASUMI Hitoshi 2461caebba [Feature #22118] Introduce Basic Bit Operations into String (#17353) 
This patch adds the following methods to String class:

* String#bit_get(offset, lsb_first: true) -> 1 | 0 | nil
* String#bit_set?(offset, lsb_first: true) -> true | false | nil
* String#bit_set(offset, lsb_first: true) -> self
* String#bit_clear(offset, lsb_first: true) -> self
* String#bit_flip(offset, lsb_first: true) -> self
* String#bit_count -> Integer
* String#bitwise_not -> String
* String#bitwise_not! -> self
* String#bitwise_and(other) -> String
* String#bitwise_and!(other) -> self
* String#bitwise_or(other) -> String
* String#bitwise_or!(other) -> self
* String#bitwise_xor(other) -> String
* String#bitwise_xor!(other) -> self

Other than implementation, tests, specs, and docs are added.

## Note

In `string.c`, I wrote some big macro that create method functions and helper
functions:

* STR_DEFINE_BINARY_BITWISE_METHOD
* STR_DEFINE_UNARY_BITWISE_KERNEL
* STR_DEFINE_BINARY_BITWISE_KERNEL

While using macros like this reduces maintainability, I believe it's acceptable
because there are no plans to extend the `bitwise_*` methods beyond this
proposal, and the logic is stable.

On the other hand, other methods such as `bit_get` and `bit_count` are planned to
have argument extensions in the future.
