Update active skill checks to compare by base gem where appropriate

[sida-wang]

Fixes #7121, fixes #7105, fixes #7146, fixes #7187.

Description of the problem being solved:

Currently skill name matching is performed on exact matches. @Paliak recently introduced logic to match against the base gem for Replica Dragonfang's Flight in #7101.

This PR updates the logic to use the gem's gameId which is the same across variants and applies the check to the "SkillName" type in modStore.lua as well as the ifSkill check in ConfigTab.lua which can be activated using the includeTransfigured option.

Implements a helper function in CalcTools.lua calcLib.getGameIdFromGemName(gemName, dropVaal) which performs lookups in data.gemForBaseName and data.gems to get the gameId. This includes a type check on the input to ensure string due to the listOrSingleIfOption function passing the entire table to the function if no table entries satisfy the condition. The dropVaal option provides a boolean option to find the base non-vaal gem of a skill which has been used throughout this PR. The option is kept in case specific scenarios are identified in the future which require Vaal gems to be treated separately to their non-Vaal counterparts.

Performed a full pass of all type = "SkillName" tags and ifSkill tags in the source code to update them to the new logic where appropriate.

Steps taken to verify a working solution:

• Tested examples from linked issues.

Non-reaper damage penalty no longer applying across variants

Tavukai and Mark of the Red Covenant now applying to SRS variants.

• Confirmed Dragonfang's behaviour still working correctly
