[ruby/prism] Support custom parser in `Prism::Translation::Parser`
Follow-up to https://github.com/Shopify/ruby-lsp/pull/1849.
This is an extension of `Prism::Translation::Parser` to implement https://github.com/Shopify/ruby-lsp/pull/1849.
It is based on the comments in https://github.com/Shopify/ruby-lsp/pull/1849#pullrequestreview-1966020868,
but also adds a default argument for delegation to `Parser::Base` super class.
Using this API, https://github.com/rubocop/rubocop-ast/pull/359 has been implemented in RuboCop AST.
As detailed in https://github.com/rubocop/rubocop-ast/pull/359, this change is expected to improve performance by 1.3x
for some source code.
Achieving a 1.3x speedup with such this simple modification is a significant improvement for Ruby LSP and its users.
