Split L2CAP Classic and LE stacks into separate modules

* Although L2CAP LE and Classic stacks look similar, they are actually very different when diving into details
* Splitting them into two separate modules will benefit in the following ways:
 * One can start a LE only stack
 * One can turn off Classic stack entirely when not needed
 * Dependencies are more obvious, e.g. LE-CoC only depends on LE L2CAP and A2DP only depends on Classic L2CAP
* Changed test names as GTEST does not allow test name collisions
* New directory structure after the change:
  - l2cap: common headers that should be exposed to public
    - internal: common internal libraries shared between LE and classic
    - classic: classic headers that should be exposed to public
      - internal: internal libraries for classic
      - cert: certification stack for classic
   - le: LE headers that should be exposed to public
      - internal: internal libraries for LE
      - cert: certification stack for LE

Using Bash
 for file in classic_*; do git mv "$file" "classic/${file/classic_/}"; done
 for file in le_*; do git mv "$file" "le/${file/le_/}"; done
 for file in internal/le_*; do git mv "$file" "le/${file/le_/}"; done
 for file in internal/classic_*; do git mv "$file" "classic/${file/classic_/}"; done
 for file in classic/*; do if [ -f "$file" ]; then sed -i -e 's/Classic//g' "$file"; fi; done
 for file in classic/internal/*; do if [ -f "$file" ]; then sed -i -e 's/Classic//g' "$file"; fi; done
 for file in le/*; do if [ -f "$file" ]; then sed -i -e 's/Le//g' "$file"; fi; done
 for file in le/internal/*; do if [ -f "$file" ]; then sed -i -e 's/Le//g' "$file"; fi; done

Using IDE:
 replace "namespace l2cap {" with "namespace l2cap { namespace classic {" in classic/
 replace "}  // namespace l2cap" with "} }" in classic/
 replace "namespace l2cap {" with "namespace l2cap { namespace le {" in le/
 replace "}  // namespace l2cap" with "} }" in le/
 replace "l2cap/classic_" with "l2cap/classic/" in classic/
 replace "l2cap/internal/classic_" with "l2cap/classic/internal/" in classic/
 replace "l2cap/le_" with "l2cap/le/" in le/
 replace "l2cap/internal/le_" with "l2cap/le/internal/" in le/
