Allow the use of the CSL in Anchor code generation.
Now it is not possible to switch from one target to the other (Native - Anchor) for methods that include a csl cpi without re-writing the CIDL code.

CIDL

- name: stake
   uses:
    - csl_spl_token.transfer_checked

Generating and building for Anchor gives the following error:

Describe the solution you'd like
Handle code generation to avoid the need of rewritings for at least each of the solana targets.

(while) Adding support to CSL, the following issues should be address or fix

• Add support for SPL Token Types #44
• using csl_spl_assoc_token namespace crashes the generator in Anchor #80
• Not recognized type in Anchor #81
• payer attr not generated for init of spl accounts #82
• SPL Token accounts generates redundant and sometimes wrong owner checks in Anchor #84
• TokenProgram.mint_to assoc_token_account param name is inadecuate #85
• TokenProg.set_authority generates a wrong type/name for the owned_pubkey param #87
• undefined deriveCslSplTokenAccount #91
