feat(EVM-emulator): add support for propagating LLVM options

[vladimirradosavljevic]

What ❔

This PR adds support for propagating LLVM options for EVM emulator. In order to propagate LLVM options, file with the same name as contract should be created with .llvm.options extension (e.g. EvmEmulator.yul.llvm.options) and this file should contain LLVM options where first and last character must be a single quote (e.g. '-eravm-jump-table-density-threshold=10').

Why ❔

To fine tune EVM emulator.

@0xVolosnikov PTAL. Please note that this currently is not working, since current version of the zksolc (1.5.0 with prerelease versionprerelease-a167aa3-code4rena) doesn't have support for --llvm-options option, so we should wait for the newest release to fully test it.

Just curious, why not possible to test with v1.5.4?

To test with v1.5.4, we need #830 + -eravm-enable-split-loop-phi-live-ranges -tail-merge-only-bbs-without-succ are not present in v1.5.4 but will be included in v1.5.5.
I tested this support with v1.5.0 and -eravm-jump-table-density-threshold=10 -tail-dup-size=4 options work like a charm.
