Investigate how to reduce Ketcher bundle size

[rrodionov91]

Background
Current js bundle size of Ketcher is 6.5MB. It leads to long initial ketcher loading time.

Solution
It needs to run bundle analyser and investigate options to reduce bundle size. Result of this ticket should be a list of other tickets related to concrete actions.

Test cases are not needed for that feature

Report from bundle analyzer:

It was generated for build with indigo without render module and dynamic import of full indigo (#5190)

[rrodionov91]

ketcher main bundle - 7.1MB

• ketcher-core - 4.2MB

  • monomers library - 2.8MB(66%)

• ketcher-react - 1.9MB

  • templates library - 530KB(27%)

• ketcher-macromolecules - 1MB

• ketcher-standalone - 200KB

miew chunk - 1.2MB (loads on demand)
ketcher-standalone with full indigo - 260KB (loads in background after indigo without render module initialisation)

—- conclusion —-

• 47% of main bundle is occupied by the library. We need to split it to separate file and load in parallel with main bundle.
• dependencies (node_modules) occupied ~15% of bundle size. We can split it into separate chunk.
