Implement MultilineStrings (#24390)

This commit adds support for multiline strings, proposed at
https://github.com/ghc-proposals/ghc-proposals/pull/569.
Multiline strings can now be written as:

    myString =
      """
      this is a
      multiline string
      """

The multiline string will have leading indentation stripped away.
Full details of this post-processing may be found at the new
GHC.Parser.String module.

In order to cleanly implement this and maximize reusability, I
broke out the lexing logic for strings out of Lexer.x into a
new GHC.Parser.String module, which lexes strings with any
provided "get next character" function. This also gave us the
opportunity to clean up this logic, and even optimize it a bit.
With this change, parsing string literals now takes 25% less
time and 25% less space.

hi: Stable sort avails

Sorting the Avails in DocStructures is required to produce fully
deterministic interface files in presence of re-exported modules.

Fixes #25104
