Fixes#6799.
Caps Lock state management for touch layouts was not quite right -- it
touched the base Caps state variables rather than just the event Lstates
property. This meant that it was impossible to track the physical Caps
Lock key separately to the touch layout layer, and that the two states
would interfere with each other.
Relates to #5816.
Moves folders under common/core/web to common/web:
* input-processor -> common/web/input-processor
* keyboard-processor -> common/web/keyboard-processor
* tools/recorder -> common/web/recorder
* tools/sentry-manager -> common/web/sentry-manager
* utils -> common/web/utils
Updates scripts and configuration to point to new folders.
