 Remove -Wtoo-many-guards from default flags (fixes #11316)

 Since #11316 indicates that having flag `-Wtoo-many-guards`
 enabled by default causes issues, the simplest thing is to
 remove it. This patch removes it from the default list, it
 updates the docs and removes the suppression flags for
 `T783` and `types/OptCoercion.hs`

 Test Plan: validate
