Improve telemetry buffering implementation

[akhenry]

Closes #7838

Describe your changes:

• Simplifies the implementation of telemetry buffering in Open MCT.
• Switches from per-parameter buffering to a shared queue. Per-parameter buffering is too easily overwhelmed by bursts of telemetry from high-frequency parameters. A single shared buffer has more overhead to grow when a burst arrives without overflowing, because the buffer is shared across all parameters.
• Removes the need for plugins to pass serialized code to a worker.
• Switched to a "one-size-fits-all" batching strategy removing the need for plugins to define a batching strategy at all.
• Captures buffering statistics for display in the PerformanceIndicator.

All Submissions:

• Have you followed the guidelines in our Contributing document?

• I would consider moving the the addEventListener('DOMContentLoaded' approach
• Don't declare the const locators if the variable is only read once
• Consider a regular label instead of aria or use arialabeledby

Small changes. Looks good otherwise.

Nice catch! Yay for tests!
