[typespec-python] typespec-python emitter long installation time

[catalinaperalta]

I was recently testing cross-language generation and noticed that the typespec-python emitter takes a long time to generate a client library compared to the other language emitters (compared with C# and TypeScript). This behavior is consistent even when attempting to generate different service specifications.

Version used: "@azure-tools/typespec-python": "0.22.4"

Specifications to test out:

• Content Safety
• Document Intelligence
• Purview DataMap

The typespec-python emitter seems to hang for a few moments, the typespec-ts and typespec-csharp emitters complete generation almost immediately.

Also, something that seems to be adding to the amount of time it takes to generate with the typespec-python emitter, is that dependency installation for this package also takes longer than other language emitters.

Following up on this, I was doing some testing on my end and it seems generating is not what takes a long time. Installing the package takes the bulk of the time when working with the typespec-python emitter.
