refactor(generators): Migrate PHP generators to TypeScript (#7647)

Browse Source 
* refactor(generators): Migrate dart_generator.js to TypeScript

* refactor(generators): Simplify getAdjusted

  Slightly simplify the implementation of getAdjusted, in part to
  make it more readable.  Also improve its JSDoc comment.

* refactor(generators): Migrate generators/php/* to TypeScript

  First pass doing very mechanistic migration, not attempting to fix
  all the resulting type errors.

* fix(generators): Fix type errors in generator functions

  This consists almost entirely of adding casts, so the code output
  by tsc should be as similar as possible to the pre-migration .js
  source files.

* fix(generators): Fix more minor inconsistencies in JS and Python

  The migration of the JavaScript and Python generators
  inadvertently introduced some inconsistencies in the code,
  e.g. putting executable code before the initial comment line that
  most generator functions begin with.  This fixes another instance
  of this (but n.b. that these inline comments should have been
  JSDocs and a task has been added to #7600 to convert them).

  Additionally, I noticed while doing the PHP migration that
  ORDER_OVERRIDES was not typed as specifically as it could be,
  in previous migrations, so this is fixed here (along with the
  formatting of the associated JSDoc, which can fit on one line
  now.)

* refactor(generators): Migrate generators/php.js to TypeScript

  The way the generator functions are added to
  phpGenerator.forBlock has been modified so that incorrect
  generator function signatures will cause tsc to generate a type
  error.

* chore(generator): Format

  One block protected with // prettier-ignore to preserve careful
  comment formatting.

  Where there are repeated concatenations prettier has made a pretty
  mess of things, but the correct fix is probably to use template
  literals instead (rather than just locally disabling prettier).
  This is one of the items in the to-do list in #7600.

* docs(generators): @fileoverview -> @file

  With an update to the wording for generators/php.ts.

* fix(generators): Fixes for PR #7647.

  - Don't declare unused wherePascalCase dictionary.
  - Don't allow null in OPERATOR dictionary when not needed.
  - Fix return type (and documentation thereof) of getAdjusted.
