Minor style fixes

See discussion at https://github.com/llvm/llvm-project/issues/139376

missing "s" for isascii and issundials

SNESLinesearch: Minor improvements

- add missing configuration options in the documentation of the line searches (some of the available options were not listed), and consistently list their respective default values

- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)

- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter

- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms

- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach

ts: TSEvaluationTimes works over multiple calls to TSSolve()

A few changes to make this work:
- Have multiple calls to `TSSetEvaluationTimes()` reset all index
counters in addition to `sol_times`

ts: TSEvaluationTimes works over multiple calls to TSSolve()

A few changes to make this work:
- Have multiple calls to `TSSetEvaluationTimes()` reset all index
counters in addition to `sol_times` and `sol_vecs`
- Move the allocation of `sol_vecs` into TSSolve itself
- At the top of `TSSolve()`, check if the initial condition has already
been written to `sol_times`

Also includes some minor renaming and comment changes
