JIT: increase inline budget (#114191)

The current JIT inline strategy is prone to running out of budget at inopportune
times, deeply inlining at some top-level sites and not inlining at all at others.
This doesn't happen all that often, but when it does it has very adverse impact
on performance.

While we await a better strategy, we can at least reduce how often this happens
by increasing the budget.

Partially addresses regressions seen in #113913
