Initialize MathPlayer when NVDA starts

[seanbudd]

Link to issue number:

Fixes #13463

Summary of the issue:

mathPres.ensureInit is called whenever math content is expected to be read, including from getTextWithFields.
This is called with every read when using UIA with Word.
If mathPlayer is not installed, this pollutes the log.
Ideally, math should be initialized at NVDA startup time.

Description of how this pull request fixes the issue:

Makes mathPlayer initialize on start up.
Removes mathPlayer.ensureInit usages from within NVDA.
External documentation referencing mathPlayer may need to be updated to reflect the need to restart NVDA after installing mathPlayer.

Testing strategy:

• Test using mathPlayer in MS Word, confirm math is read
• Test that if mathPlayer is not installed, a warning is logged at startup but at no other time.

Known issues with pull request:

None

Looks good. I confirmed NVDA's MathPlayer support still functions after this change. E.g. I was able to read and interact with math in MS Word.

Just a thought, should mathPres also be terminateable as well as be terminated/initialized in core.resetConfiguration?
