* Revert "Create FoundationInternals, an internal module to host shared files used by FoundationInternationalization and FoundationEssentials (#101)"
This reverts commit 8f08a649db1f3eb31593cdae7a30c5e95cb614a7.
* Reapply fb718cd3fb9f058a5fd6d736cec9c2b99d6f7dc6 fix to the other restored LockedState
* Create FoundationInternals, an internal module to host shared files used by FoundationInternationalization and FoundationEssentials
- Modules will access FoundationInternals types with `package import FoundationInternals`. This is currently an experimental feature of `AccessLevelOnImport`.
- Move `LockedState` to FoundationInternals and publicize functions needed by other modules.

- Move localized uppercase and lowercase to FoundationLocalization
- if-def out of CharacterSet from FoundationPreview. It's not implemented at all there, and having a no-op stub is misleading
* rdar://107955097 (FoundationPreview: Batch move string API (continued))
- Move components separated by string and range of string functions
* rdar://107955097 (FoundationPreview: Batch move string API (continued))
Enable snake case options for JSON encoder and decoder. We haven't been able to enable this option because it needed `CharacterSet`, which hasn't been properly implemented for FoundationPreview. Now that we have `BuiltInUnicodeScalarSet`, which mirrors `CharacterSet`, we can switch to that and enable the options.
* rdar://107955097 (FoundationPreview: Batch move string API (continued))
- Move `StringProtocol.lineRange(for:)` and `paragraphRange(for:)` to FoundationEssentials
- Rename String+Regex.swift to RegexPatternCache.swift
- Consolidate extensions on various String family members and remove one redundant swift file
