Code formatting

[apple1417]

The SDK codebase is a mess of code styles, since it's been passed between so many authors without proper standardization. We should define a standard, and format it to fix.

Tracking:

• Decide on convention and create config for editorconfig/clang format/others
• C++ Code formatting
  • Github check for formatting
• One class/module per file
• Document all functions/types
  • Github check for documentation

Looking at the following .clang-format

---
Language:        Cpp
BasedOnStyle:    Chromium
ColumnLimit:     100
SortIncludes:    CaseInsensitive
UseTab:          ForContinuationAndIndentation
IndentWidth:     4
TabWidth:        4
InsertBraces:    true
---

Visual studio can pull settings from this file, so we don't need a separate .editorconfig.

InsertBraces relies on clang format version 15, the first release candidate of which is coming out shortly. This issue is on hold until then.
