std.unicode: Refactor and add WTF-16/WTF-8 functions

Browse Source

Renamed functions for consistent `Le` capitalization and conventions:

- utf16leToUtf8Alloc -> utf16LeToUtf8Alloc
- utf16leToUtf8AllocZ -> utf16LeToUtf8AllocZ
- utf16leToUtf8 -> utf16LeToUtf8
- utf8ToUtf16LeWithNull -> utf8ToUtf16LeAllocZ
- fmtUtf16le -> fmtUtf16Le

New UTF related functions:

- utf16LeToUtf8ArrayList
- utf8ToUtf16LeArrayList
- utf8ToUtf16LeAlloc
- isSurrogateCodepoint

(the ArrayList functions are mostly to allow the Alloc and AllocZ to share an implementation)

New WTF related functions/structs:

- wtf8Encode
- wtf8Decode
- wtf8ValidateSlice
- Wtf8View
- Wtf8Iterator
- wtf16LeToWtf8ArrayList
- wtf16LeToWtf8Alloc
- wtf16LeToWtf8AllocZ
- wtf16LeToWtf8
- wtf8ToWtf16LeArrayList
- wtf8ToWtf16LeAlloc
- wtf8ToWtf16LeAllocZ
- wtf8ToWtf16Le
- wtf8ToUtf8Lossy
- wtf8ToUtf8LossyAlloc
- wtf8ToUtf8LossyAllocZ
- Wtf16LeIterator
