* Double curly braces when parsing FormattableString

Interpolation expressions have already been replaced by %P() at this
point, so it should be safe and should only undo the opposite
transformation done by lexer.

* Refactor to make the intention clearer

* Enable the fix only for langpreview

* Fix test

* Allow simple arithmetic in number literals (behind a lang feature flag)

Interpolated strings require escaping '%' chars by doubling them,
however if an interpolated string literal had no interpolation
expressions, it would not drop extra '%' chars in the content.

The problem was that we had some cached lexer state when reading new
input during FSI session. If lexer threw an error on a very first token
of new input, the cached lexer state would not get updated, so we would
assosciate old lexer state with this new token that caused an error.

Now we will invalidate that cached state at the begining of reading new
input.

* Add attribute to prevent fsc inlining but allow JIT inlining
* Work around IL checker shortcomings
* Update surface area
* Rename NoFscInliningAttribute

* Pop string nesting before error in nested quotes

* Cover more cases of incomplete interpolation

* Add tests for unmatched curly brace

Two tests for unmatched curly brace in interpolated string

* Split tests into separate cases

This splits two unit tests that were testing multiple cases in one go
into multiple unit tests - one per each case.

Note, that original tests were expecting an accurate error for each
of multiple lines of malformed string literals. They would no longer
pass with changes introduced by previous commits in this PR.
