Removed redundant programming mode events and updated TC documentation.

These events were made redundant by the introduction of the `TargetState`
struct, and the `TargetStateChanged` event.

 `TargetControllerService::enableProgrammingMode()`).

+has been disabled.
 
-For example, the `ResumeTargetExecution` command returns `true` here, as it attempts to control program flow on the
-target, which can only be done when the target is not in programming mode:
-
-```c++
-class ResumeTargetExecution: public Command
-{
-public:
-    // ...
-    [[nodiscard]] bool requiresDebugMode() const override {
-        return true;
-    }
-};
-```
-
-On the other hand, the `ReadTargetMemory` command will only return `true` if we're reading from RAM, as RAM is the
-only memory which isn't accessible when the target is in programming mode:
-
-```c++
-class ReadTargetMemory: public Command
-{
-public:
-    Targets::TargetMemoryType memoryType;
-    Targets::TargetMemoryAddress startAddress;
-    Targets::TargetMemorySize bytes;
-
-    // ...
-
-    [[nodiscard]] bool requiresDebugMode() const override {
-        return this->memoryType == Targets::TargetMemoryType::RAM;
-    }
-};
-```
-
-The TargetController will emit `ProgrammingModeEnabled` and `ProgrammingModeDisabled` events when it enables/disables
-programming mode. Components should listen for these events to ensure that they disable any means for the user to trigger
-debugging operations whilst programming mode is enabled. For example, the Insight component will disable much of its
-GUI components when programming mode is enabled.
-
-It shouldn't be too much of a problem if a component attempts to perform a debug operation on the target whilst
-programming mode is enabled, as the TargetController will just respond with an error. But still, it would be best to
-avoid doing this where possible.
+The TargetController will emit a `TargetStateChanged` event when programming mode is enabled/disabled. See 
+[`TargetState::mode`](../Targets/TargetState.hpp) for more.
