[2201.11.0-stage] Refactor strand dump logic and fix bug

[ravinperera00]

Purpose

Occasionally, when trying to generate a strand dump report, the user runs into an IndexOutOfBoundsException. This PR intends to fix that issue and also refactor the code to improve readability and the scope of the stand dump report.

Approach

• Fix
  When parsing the generated Java thread report, there can be cases where a virtual thread is present but its relevance to Ballerina cannot be established. Then, details about that thread won't be added to the list of Ballerina Strand details. Therefore, it is wrong to assume that the balStand array will have a 1:1 mapping for each id generated during the parsing resulting in an IndexOutOfBoundsException. This can be mitigated but using a Map with the id as the key instead of using an ArrayList.

• Refactoring
  Broaden the scope of identifiers so that important ballerina related strands aren't missed.
