Remove calling APIs for returning units for specific types

[ansnfernand]

📝 Description of the feature

Don't use the following APIs since ListUnits(UnitType) can be used:

Stackup service

• ListLaminateThicknessUnits

Lifecycle service

• ListFreqUnits (not found in PySherlock)
• ListTempUnits (not found in PySherlock)
• ListAmplUnits
• ListShockLoadUnits

💡 Steps for implementing the feature

These units are used for validation of parameters in PySherlock.
Remove this validation (and associated unit tests).
Remove the code that is making requests and caching these units.

Bench test to determine if Sherlock is handling invalid units. If not, create Sherlock stories to address that.
